Communication Killers

6 Communication Killers That Destroy Relationships (and How to Fix Them)

Every couple argues. That is normal. What determines whether a relationship survives conflict is not whether you fight, but how you fight. After decades of research studying thousands of couples, Dr. John Gottman and Dr. Julie Gottman identified six communication patterns that are the most reliable predictors of relationship breakdown.

The first four are so destructive that the Gottmans call them the “Four Horsemen of the Apocalypse”: Criticism, Contempt, Defensiveness, and Stonewalling. The remaining two, Belligerence and Blame, are what the Gottmans refer to as the Horsemen’s cousins. Belligerence shares Contempt’s quality of dominance and superiority. Blame is closely tied to both Criticism and Defensiveness. All six can poison a relationship if left unchecked.

As a Gottman Level II trained couples therapist, I see these patterns regularly in my work with couples. The good news is that every one of them has an antidote. Recognizing these patterns in your own relationship is the first step toward changing them.

1. Criticism (Horseman #1)

Criticism is when you attack your partner’s character instead of addressing a specific behavior. It is the difference between “I was frustrated that the kitchen was still messy when I got home” and “You are so lazy. You never clean up after yourself.”

Notice the language. Criticism tends to include words like “always” and “never.” It paints your partner as fundamentally flawed rather than as someone who did something that bothered you. While criticism is considered the least damaging of the Four Horsemen on its own, it is often the entry point. Once criticism becomes a habit, it opens the door for the others to follow.

It is worth understanding that underneath most criticism is a legitimate complaint. The problem is the delivery, not the feeling behind it. When someone criticizes, they are usually trying to express a need that is not being met. They are just doing it in a way that guarantees a defensive response.

The antidote: Use a gentle startup

Instead of leading with an attack on character, express what you feel and what you need. “I feel overwhelmed when I come home and the kitchen is messy. Could we figure out a system that works for both of us?” This approach creates a 98% higher likelihood of a productive conversation, according to Gottman research. It keeps the focus on the issue rather than on your partner’s worth as a person.

2. Contempt (Horseman #2)

Contempt is the single greatest predictor of divorce. It goes beyond criticism into territory that communicates disgust, disrespect, and superiority. When contempt is present, you will see eye-rolling, sarcasm, mockery, name-calling, and hostile humor. The person expressing contempt is essentially saying, “I am better than you, and you are beneath me.”

Contempt does not appear out of nowhere. It builds over time from a long history of unresolved negative thoughts about your partner. When resentment accumulates and is never addressed, it eventually curdles into contempt. And once contempt becomes a regular feature of how you communicate, the relationship is in serious danger.

The antidote: Build a culture of appreciation

Contempt thrives in relationships where partners have stopped noticing what is going well. The antidote is deliberately cultivating fondness and appreciation. This means actively looking for things your partner does right and telling them. It means remembering why you chose this person in the first place. It also means catching yourself when contempt starts to surface and choosing to express your frustration through a direct complaint rather than through mockery or disdain.

3. Defensiveness (Horseman #3)

Defensiveness is the instinct to protect yourself when you feel attacked. It typically shows up as making excuses, shifting blame, or playing the victim. When your partner says, “You forgot to call me,” and you respond with, “Well, you never call me either,” that is defensiveness. You are deflecting responsibility instead of hearing the concern.

The problem with defensiveness is that it tells your partner their feelings do not matter. It shuts down the conversation and sends the message that you are more interested in protecting yourself than understanding their experience. Even when the criticism coming at you is unfair, responding with defensiveness almost always makes things worse.

There is also a subtler version worth recognizing: anticipatory defensiveness. This is when you start mentally preparing your rebuttal before any criticism has actually been made. You see your partner’s facial expression, make an assumption about what they are about to say, and build your defensive case before a single word has been spoken. You are reacting to a conflict that only exists in your head. My mother used to call this “borrowing trouble,” which is a remarkably accurate description of what is happening.

The antidote: Accept responsibility for your part

You do not have to accept blame for everything. But acknowledging even a small piece of the problem signals to your partner that you are willing to engage honestly. “You are right, I did forget to call. I am sorry about that.” That one sentence can completely change the trajectory of a conversation. It lowers the temperature and creates space for real dialogue instead of a defensive back-and-forth.

4. Stonewalling (Horseman #4)

Stonewalling is when one partner shuts down and disengages from the conversation entirely. They may go silent, leave the room, stare blankly, or give one-word responses. From the outside, it looks like they do not care. From the inside, it is usually the opposite. They care so much that they have become physiologically overwhelmed.

The Gottman Institute calls this state Diffuse Physiological Arousal (DPA). When your heart rate exceeds about 100 beats per minute during a conflict, your body’s fight-or-flight system activates and your ability to think clearly, listen empathetically, or respond constructively drops dramatically. Stonewalling is often a self-protective response to that flooding, not a deliberate choice to be dismissive.

That said, the impact on the other partner is the same regardless of the intention. Being stonewalled feels like being abandoned in the middle of an important conversation.

The antidote: Take a structured break

When you notice flooding happening, either in yourself or your partner, call a time-out. The key is to do this constructively rather than just walking away. Be specific: “I need a break. I want to finish this conversation, but I need 20 minutes to calm down first. Can we come back to this at 7:30?”

The break should be at least 20 minutes (that is how long it takes for your nervous system to settle down) but no longer than 24 hours. During the break, do something that genuinely calms you. Breathing exercises, a walk, music, or anything that brings your heart rate down. Do not use the break to rehearse your argument. The goal is to return to the conversation in a state where you can actually hear each other.

Some couples find it helpful to have a neutral code word or gesture to signal the need for a break without it feeling like an attack. The word itself does not matter as long as both partners agree on it in advance and honor it when it is used.

5. Belligerence (Cousin of Contempt)

Belligerence is one of the two “cousins” of the Four Horsemen. Like Contempt, it is rooted in dominance and superiority, but it expresses itself as aggression disguised as a dare. The belligerent partner comes across as looking for a fight, provoking the other person, or challenging them in a way that is designed to escalate rather than resolve.

An example: one partner says, “Could you help me with the dishes?” The belligerent response: “What are you going to do if I say no? Go ahead, I dare you.”

Belligerence is fundamentally a power move. The person using it is trying to establish dominance in the conversation by making the other person feel unsafe or intimidated. It poisons the environment for any kind of honest communication.

The antidote: Make a repair attempt

Repair attempts are any action or statement that de-escalates a conflict and signals a willingness to work toward a solution. They can be as simple as, “That came out wrong. Can we start over?” or “This got really heated and that is not what either of us wants. Let’s take a break and try again.”

The repair attempt does not need to be eloquent. It just needs to be genuine. What matters is that it communicates accountability and a desire to reconnect rather than continuing to escalate.

6. Blame (Cousin of Criticism and Defensiveness)

Blame is the second cousin of the Horsemen. It is the attempt to shift the entire burden of responsibility onto the other person. When blame is operating, neither partner is able to look honestly at their own contribution to the problem. Everything becomes the other person’s fault.

Blame is closely related to both criticism and defensiveness, but it has its own particular quality. The person doing the blaming is usually in genuine pain and is trying to discharge that pain by directing it outward. As researcher Brene Brown has pointed out, blame gives us a sense of control in moments when we feel powerless. But that sense of control is an illusion, and it comes at the cost of the relationship.

Often, when you look more closely at a pattern of blame, you find that the person doing it is longing for something they cannot quite articulate. When their partner is willing to share some of the weight of the tension rather than fighting over whose fault it is, the real conversation can begin.

The antidote: Accept responsibility for your part

This is the same antidote as defensiveness, and for good reason. Blame and defensiveness are two sides of the same coin. When one partner accepts even partial responsibility, it breaks the cycle. “I can see how my part in this made things harder” is often enough to shift the dynamic from adversarial to collaborative.

Building Better Communication

Knowing the six patterns that destroy communication is only half the picture. Recognizing contempt when it shows up is useful. But you also need something to replace it with. The couples who do well in the Gottman research are not couples who never slip into criticism or defensiveness. They are couples who have built enough skill in the other direction that the repairs happen quickly and the positive interactions far outweigh the negative ones.

Here is what the constructive side of communication actually looks like in practice.

Make Yourself Listenable

Most people think about communication as a speaking problem: how do I say the right thing, how do I get my point across, how do I make the other person understand. But the biggest communication breakdowns happen because one or both people have become difficult to listen to, and neither of them realizes it.

Being listenable means your partner can take in what you are saying without their defenses activating. That is a higher bar than just being technically correct. You can be right about every word and still deliver it in a way that makes the other person shut down.

Use “I” statements that are actually about you. The concept is familiar. Instead of “You never help around the house,” say “I feel overwhelmed when I’m doing everything myself.” But the common mistake is turning an I-statement into a dressed-up accusation. “I feel like you don’t care” is not an I-statement. It is a judgment about the other person with “I feel” stapled to the front. A real I-statement describes your own emotional experience: “I feel disconnected from you lately, and I miss feeling like we’re a team.” The test is simple: does the sentence contain an accusation? If it does, it is not an I-statement regardless of how it starts.

Keep it to one issue. When couples have been sitting on frustration for a while, the conversation often becomes a catalog of grievances. You start with the dishes and end up relitigating a fight from three months ago. This is called kitchen-sinking, and it is one of the fastest ways to make yourself unlistenable. Your partner cannot respond to seven complaints at once. Pick the one that matters most right now and stay there.

Watch your timing. Bringing up a serious issue when your partner is walking in the door, falling asleep, or already stressed about something else is setting the conversation up to fail. A useful habit is to ask “Is this a good time to talk about something?” It takes five seconds and dramatically increases the odds that the other person can actually hear you.

Listen Like You Mean It

Active listening is one of those concepts that gets taught so often it has become almost meaningless. Everyone knows they should “listen actively.” Very few people do it consistently, especially in conflict.

Real listening in a relationship is not waiting for your turn to talk. It is not formulating your rebuttal while the other person is still speaking. It is not nodding while your internal monologue runs a parallel track of counterarguments.

Reflect before responding. Before you give your perspective, show that you understood theirs. “So you’re saying that when I made plans without checking with you, it felt like I wasn’t considering you.” This does not mean you agree. It means you heard them. The Gottman research shows that couples who feel heard by their partner during conflict resolve issues faster and with less damage to the relationship, even when they disagree on the outcome.

Ask questions that are genuinely curious. “What was that like for you?” or “Help me understand what you mean by that” opens a conversation. “So what exactly do you want me to do about it?” closes one. The difference is whether the question is seeking understanding or scoring a point.

Tolerate the discomfort of hearing something you do not like. This is the hardest one. When your partner says something that triggers defensiveness, the impulse is to interrupt, correct, or explain. Letting them finish, even when what they are saying feels inaccurate or unfair, is a skill that takes practice. You will get your turn. But if you cut them off to defend yourself, the conversation shifts from problem-solving to self-protection, and nothing gets resolved.

Repair Early and Often

The Gottmans found that what separates happy couples from unhappy ones is not the absence of conflict but the presence of repair attempts. A repair attempt is any gesture, verbal or nonverbal, that tries to de-escalate tension during an argument. It can be humor (“I think we just activated Horseman number three”), a direct acknowledgment (“I’m getting defensive, give me a second”), a physical gesture (reaching for a hand), or simply saying “Can we start over? I came in too hot.”

Repair attempts only work if the other person accepts them. If your partner makes a joke to lighten the tension and you respond with “This isn’t funny,” you have rejected the repair. Over time, rejected repair attempts teach both people that trying to fix things during a fight is pointless, and that is when conversations start escalating without a safety net.

If you recognize your relationship in any of the six patterns described above, or if the constructive skills in this section sound like things you used to do but have stopped doing, that is useful information. It tells you where the work is.

These Patterns Do Not Just Affect Romantic Relationships

The Gottmans have been clear that these six patterns can poison any relationship, not just romantic ones. They show up between parents and children, between friends, between coworkers, and between family members. If you recognize these patterns in any of your important relationships, the antidotes apply universally.

When to Get Help

If these patterns have become deeply entrenched in your relationship, reading about them is a good start, but it may not be enough to change them on your own. These dynamics are often self-reinforcing. One partner’s criticism triggers the other’s defensiveness, which triggers stonewalling, which triggers contempt, and the cycle continues.

Couples therapy creates a space where both partners can learn to interrupt these patterns with the support of a trained third party. As a Gottman Level II trained therapist, I work with couples to identify which of these patterns are doing the most damage and build specific skills to replace them with healthier alternatives.
