Destructive behaviour in a relationship can be painful, confusing, and exhausting. Sometimes it shows up as constant criticism, defensiveness, blame, withdrawal, jealousy, resentment, emotional distance, repeated arguments, or patterns that leave both people feeling hurt and misunderstood.
In some relationships, these patterns are obvious. In others, they build slowly over time. You may love your partner and still feel stuck in a cycle that keeps damaging trust, closeness, communication, and emotional safety.
This article explains what destructive behaviour in relationships can look like, why it happens, what can help, and when couples counselling may be useful. It also explains when the issue may be more serious than relationship conflict and may require safety planning or specialized support.

What does destructive behaviour in a relationship mean?
Destructive behaviour in a relationship refers to patterns that repeatedly damage trust, respect, communication, safety, or connection between partners. These behaviours may be intentional or unintentional. They may come from fear, insecurity, past experiences, poor communication habits, emotional overwhelm, anger, avoidance, or unresolved hurt.
Some people search for “destructive person meaning” when they are trying to understand what is happening in their relationship. A more helpful way to frame it is this: the problem is usually not that one person is simply “destructive.” The problem is often a destructive pattern that needs to be understood and changed.
That distinction matters. Labelling someone as a destructive person can create more blame and defensiveness. Looking at destructive behaviour can help both partners ask better questions:
- What keeps happening between us?
- What triggers the pattern?
- How do we each respond when we feel hurt, afraid, criticized, rejected, or overwhelmed?
- What do we need to change to rebuild safety and trust?
In many relationships, destructive behaviour is not one single event. It is a cycle that repeats.
Signs of destructive behaviour in relationships
Destructive relationship patterns can look different from couple to couple, but some signs are common.
You may be dealing with destructive behaviour if you notice:
- the same arguments happening again and again
- criticism that attacks character instead of addressing behaviour
- defensiveness whenever concerns are raised
- contempt, sarcasm, mocking, eye-rolling, or name-calling
- stonewalling, shutting down, or refusing to engage
- threatening to leave during conflict
- using silence, withdrawal, or affection as punishment
- keeping score or bringing up old mistakes repeatedly
- checking a partner’s phone, location, or messages without consent
- jealousy or mistrust that becomes controlling
- lying, hiding, or avoiding difficult conversations
- physical or emotional cheating
- refusing to take responsibility for harm
- escalating conflict instead of repairing it
- feeling like you have to walk on eggshells
One difficult part is that destructive behaviour can become normalized. If the relationship has been stuck in the same pattern for a long time, both people may start to believe this is just “how we are.” But repeated conflict, fear, disconnection, resentment, or emotional shutdown does not have to be the only option.
Destructive behaviour versus abuse
Not every destructive relationship pattern is abuse. Many couples struggle with poor communication, emotional reactivity, defensiveness, avoidance, or unresolved resentment without one person trying to control or dominate the other.
However, some behaviours go beyond unhealthy conflict. If there is fear, intimidation, coercive control, threats, violence, sexual pressure, financial control, isolation, stalking, or one partner repeatedly using power to control the other, safety needs to come first.
Couples therapy is not always appropriate when abuse or coercive control is present. In those situations, individual support, safety planning, crisis resources, or specialized family violence services may be more appropriate.
Consider seeking specialized help if your relationship includes:
- physical violence or threats of violence
- fear of what your partner will do if you disagree
- being isolated from friends, family, money, transportation, or support
- being monitored, followed, tracked, or controlled
- sexual coercion or pressure
- threats involving children, pets, housing, immigration, finances, or reputation
- being prevented from leaving, working, studying, or accessing help
The Government of Canada provides information on safety planning if you are in an abusive relationship. If you are in immediate danger, call 911.
Common destructive communication patterns
Many destructive relationship patterns show up during conflict. The Gottman Institute describes four common conflict patterns as criticism, contempt, defensiveness, and stonewalling.
Criticism
Criticism attacks the person instead of addressing the issue. It often sounds like “you always,” “you never,” or “what is wrong with you?”
For example:
- “You never care about anyone but yourself.”
- “You are so lazy.”
- “You always ruin everything.”
A healthier version focuses on the specific behaviour, feeling, and need:
- “When the dishes are left overnight, I feel overwhelmed. Can we make a plan for cleanup after dinner?”
Contempt
Contempt includes disrespect, mockery, sarcasm, eye-rolling, name-calling, ridicule, or speaking from a position of superiority. It is especially damaging because it communicates disgust or disrespect rather than a wish to solve the problem.
Contempt can sound like:
- “You are pathetic.”
- “Of course you messed this up.”
- “I should have known better than to trust you.”
If contempt has become common, the relationship likely needs intentional repair. Both partners may need to rebuild respect, appreciation, accountability, and emotional safety.
Defensiveness
Defensiveness happens when a concern is met with excuses, counterattacks, denial, or blame. It is understandable to want to protect yourself when you feel accused, but constant defensiveness makes it hard to solve problems.
Defensiveness can sound like:
- “It is not my fault.”
- “You do the same thing.”
- “You are too sensitive.”
- “I only did that because of you.”
A healthier response might sound like:
- “I can see why that hurt you. I was frustrated, but I still need to take responsibility for how I said it.”
Stonewalling
Stonewalling happens when someone shuts down, withdraws, stops responding, leaves the conversation, or refuses to engage. Sometimes this is done to punish the other person. Other times, it happens because the person feels overwhelmed and does not know how to stay present.
Stonewalling can look like:
- silent treatment
- leaving without saying when you will return
- refusing to answer
- checking out emotionally
- pretending nothing happened after a serious conflict
If someone is overwhelmed, a structured break can be helpful. The key is to name the break and return to the conversation later.
For example:
- “I am getting overwhelmed and I do not want to say something hurtful. I need 20 minutes, and then I will come back so we can keep talking.”
What causes destructive relationship patterns?
Destructive behaviour does not usually come from nowhere. It often develops from a combination of emotional habits, past experiences, relationship stress, unmet needs, and protective responses.
Possible contributors can include:
- fear of rejection or abandonment
- past betrayal or trust injuries
- childhood trauma or unstable family relationships
- poor conflict modelling growing up
- anxiety, depression, anger, or stress
- unresolved resentment
- attachment fears
- difficulty identifying or expressing emotions
- feeling unheard, dismissed, or unimportant
- substance use or other coping patterns
- major life stress such as parenting, finances, grief, illness, work pressure, or burnout
Understanding the cause does not excuse harmful behaviour. It helps explain what needs attention if the relationship is going to change.
Self-sabotage in relationships
Sometimes destructive behaviour is connected to self-sabotage. This can happen when someone deeply wants closeness but also feels afraid of it.
Self-sabotage in a relationship can look like:
- picking fights when things are going well
- testing a partner’s love or loyalty
- pulling away when the relationship feels serious
- expecting rejection before it happens
- assuming your partner has bad intentions
- comparing your partner to past partners
- feeling undeserving of a healthy relationship
- ending the relationship before you can be hurt
These patterns may begin as protection. If someone has been hurt, abandoned, betrayed, criticized, or emotionally unsafe in the past, closeness can feel risky. The person may unconsciously create distance to avoid being hurt again.
Therapy can help people understand these patterns without shame and begin responding differently.
How destructive patterns affect emotional safety
Emotional safety means both people can bring up concerns, express feelings, set boundaries, make mistakes, and ask for needs without fear of being humiliated, punished, dismissed, or attacked.
Destructive behaviour erodes emotional safety. Over time, partners may stop being honest. They may avoid hard conversations, hide feelings, withdraw affection, or assume the worst about each other.
Signs emotional safety may be damaged include:
- you avoid bringing up concerns because it will become a fight
- you feel nervous before difficult conversations
- you hide your feelings to keep the peace
- you expect criticism or defensiveness
- you feel lonely even when you are together
- you do not trust repair after conflict
- you feel like small issues become major arguments
Rebuilding emotional safety takes consistency. Apologies help, but repeated changed behaviour matters more.
Can destructive relationship patterns be changed?
Yes, some destructive relationship patterns can change, especially when both people are willing to take responsibility, communicate differently, and practise new responses over time.
Change is more likely when both partners can:
- recognize the pattern without blaming everything on one person
- take responsibility for their own behaviour
- listen without immediately defending
- repair after conflict
- set boundaries without threats or punishment
- work on individual triggers and coping skills
- seek help before resentment becomes too deep
Change is harder when one person refuses accountability, continues to use intimidation or control, minimizes harm, or expects the other partner to do all the work.
How to start changing destructive behaviour
If you recognize destructive behaviour in your relationship, start with awareness and small changes. You do not have to solve the entire relationship at once.
1. Name the pattern, not just the argument
Instead of focusing only on the latest fight, ask what pattern keeps repeating.
For example:
- “We both get defensive when money comes up.”
- “I shut down when I feel criticized.”
- “We escalate quickly when either of us feels unheard.”
- “We keep arguing about chores, but underneath that we both feel unappreciated.”
When couples can name the pattern, they can begin working against the cycle together.
2. Slow down conflict
Destructive behaviour often happens when conflict moves too quickly. People react before they understand what they are feeling or needing.
Try slowing the conversation down by saying:
- “I want to understand this, but I am getting reactive.”
- “Can we pause for a few minutes and come back to this?”
- “I am hearing this as criticism, but I want to check if that is what you mean.”
- “I care about this conversation and I do not want it to turn into another fight.”
Slowing down does not mean avoiding the issue. It means creating enough space to respond instead of react.
3. Replace blame with specific requests
Blame often leads to defensiveness. Specific requests make it easier to understand what needs to change.
Instead of:
- “You never help.”
Try:
- “I feel overwhelmed doing bedtime alone. Can we divide bedtime tasks tonight?”
Instead of:
- “You do not care about me.”
Try:
- “I felt hurt when you looked at your phone while I was talking. Can we put phones away for this conversation?”
4. Take responsibility for your part
Taking responsibility does not mean accepting blame for everything. It means being honest about your own behaviour.
Useful responsibility statements include:
- “I raised my voice, and that was not okay.”
- “I got defensive instead of listening.”
- “I withdrew without telling you I needed a break.”
- “I made an assumption instead of asking.”
- “I can understand why that hurt you.”
Responsibility is one of the foundations of repair.
5. Repair sooner
All couples have conflict. The difference is often whether repair happens.
Repair can include:
- apologizing clearly
- acknowledging the impact of your behaviour
- asking what your partner needs now
- explaining what you will do differently next time
- returning to the conversation after a break
- showing care through consistent action
A repair attempt does not erase what happened, but it can help rebuild trust when it is sincere and followed by changed behaviour.
6. Set boundaries without punishment
Boundaries are not threats. A healthy boundary communicates what you need and what you will do to protect your wellbeing.
For example:
- “I want to talk about this, but I will not stay in a conversation where we call each other names.”
- “If we start yelling, I am going to take a 20-minute break and come back.”
- “I need us to speak respectfully, even when we disagree.”
Boundaries should not be used to control, punish, or manipulate the other person.
When couples therapy may help
Couples therapy may help when both partners want to understand the relationship pattern and work toward healthier communication, repair, trust, and connection.
Couples counselling can help with:
- repeated arguments
- communication breakdowns
- emotional distance
- resentment
- trust concerns
- conflict about parenting, money, intimacy, family, or responsibilities
- difficulty repairing after hurt
- feeling stuck in the same cycle
- deciding whether the relationship can move forward
At Your Counselling, couples therapy can provide a structured space to slow down conflict, understand what each person is experiencing, and practise new ways of responding.
When individual counselling may be the better starting point
Sometimes individual counselling is the better first step. This may be true if one partner is unsure what they want, if the relationship feels unsafe, if one person wants to understand their own patterns, or if there are concerns such as anxiety, depression, trauma, anger, addiction, or self-worth.
Individual therapy can help you explore:
- why certain situations trigger strong reactions
- how past experiences may affect current relationships
- your boundaries and needs
- whether the relationship feels safe and healthy
- how to communicate more clearly
- how to stop repeating patterns that hurt you or your partner
If you are not sure whether to start alone or with your partner, individual counselling can be a useful place to sort through what is happening.
What if destructive behaviour affects the whole family?
Relationship conflict can affect children, teens, extended family, and the overall emotional tone of the home. Even when adults try to keep conflict private, family members may still sense tension, withdrawal, criticism, or emotional unpredictability.
Family support may be helpful when destructive patterns affect parenting, co-parenting, communication with children, blended family dynamics, or repeated conflict in the home.
Your Counselling offers family therapy for families who want support with communication, conflict, transitions, stress, and relationship patterns.
How anxiety, trauma, or anger can affect relationship patterns
Destructive relationship behaviour can sometimes be connected to other mental health concerns.
Anxiety can make uncertainty, conflict, silence, or distance feel threatening. Trauma can make closeness, criticism, rejection, or vulnerability feel unsafe. Anger can become a protective response when someone feels hurt, powerless, ashamed, or overwhelmed.
These concerns do not excuse harmful behaviour, but they may help explain why certain patterns repeat.
Depending on what is happening, support may include help with anxiety, trauma-informed therapy, or anger management counselling.
What if only one partner wants to change?
It is common for one partner to be more ready for change than the other. This can be painful and frustrating.
If only one partner wants help, you can still work on your own patterns, boundaries, communication, and clarity. You can learn to respond differently, decide what you will and will not accept, and explore what a healthier relationship would require.
However, one person cannot single-handedly create a healthy relationship if the other person refuses accountability, continues harmful behaviour, or is unwilling to participate in repair.
How to know if the relationship is improving
Progress is not always instant. A relationship may still have conflict while both people are learning new patterns.
Signs of improvement can include:
- conflict becomes less frequent or less intense
- both people take responsibility faster
- repair happens sooner
- partners listen with less defensiveness
- there is less contempt, sarcasm, or name-calling
- boundaries are respected
- both people feel safer bringing up concerns
- there is more warmth, appreciation, or connection
- changed behaviour becomes more consistent over time
A healthier relationship is not one without conflict. It is one where conflict can be handled with respect, honesty, accountability, and care.

Frequently asked questions about destructive behaviour in relationships
What is destructive behaviour in a relationship?
Destructive behaviour in a relationship refers to repeated patterns that damage trust, respect, emotional safety, communication, or connection. This can include criticism, contempt, defensiveness, withdrawal, control, lying, blame, self-sabotage, or repeated conflict that never gets repaired.
What does destructive person mean in a relationship?
Some people use the phrase destructive person to describe someone whose behaviour repeatedly harms the relationship. A more useful approach is to focus on the specific destructive behaviours, such as criticism, stonewalling, defensiveness, control, or repeated betrayal, rather than labelling the whole person.
What are signs of self-sabotage in relationships?
Signs of self-sabotage can include picking fights when things are going well, pulling away when the relationship gets closer, expecting rejection, testing a partner’s loyalty, ending relationships suddenly, or assuming your partner has bad intentions without clear evidence.
Can destructive relationship patterns be fixed?
Some destructive relationship patterns can improve when both partners are willing to take responsibility, communicate differently, repair after conflict, respect boundaries, and seek support when needed. Change is harder when one person refuses accountability or continues controlling, abusive, or unsafe behaviour.
When should couples therapy be considered?
Couples therapy may be helpful when partners are stuck in repeated arguments, communication breakdowns, resentment, emotional distance, trust concerns, or conflict patterns they cannot resolve on their own. It works best when both people are willing to participate honestly and safely.
Is couples therapy appropriate if there is abuse?
Couples therapy may not be appropriate when there is abuse, coercive control, intimidation, threats, or violence. In those situations, safety planning, individual support, crisis resources, or specialized family violence services may be the better starting point.
What if only one partner wants counselling?
If only one partner wants counselling, individual therapy can still help. It can support you in understanding your patterns, boundaries, triggers, communication, and choices. However, one person cannot create a healthy relationship alone if the other person refuses accountability or continues harmful behaviour.
