All couples fight, but not every couple knows how to do it in a healthy way. Further, in the heat of an intense argument, it’s human nature to slip into familiar patterns of communication no matter how ineffective they may be. Your conflict style—including your go-to moves in any fight—can hurt your relationship and erode trust over time.

The Gottman Method pulls from more than 40 years of relationship study by Dr. John Gottman. Along with his wife Dr. Julie Schwartz Gottman, they found the keys to long-lasting relationships with significant emphasis on how couples navigate conflict. This means, if you want to stay together for the long haul, you have to learn how to talk to each other when you don’t agree.

Based on their findings, here are four signs that the way you fight is hurting your chances at a healthy partnership.

You’re critical

Criticism strikes at the character of your partner. It feels like a personal attack. Whether or not it’s intentional, when you’re critical, you take your anger off of the situation or the issue and aim it at your partner. The target becomes who your partner is as a person.

Examples of criticism are:

“You never help around here.”

“You’re always taking her side.”

“Why can’t you be more thoughtful?”

You’re mean-spirited

Drs. John and Julie Gottman call this contempt. It’s when you are disrespectful and purposely hurtful. Caught up in the emotion of the moment, you engage in name-calling, ridicule, mocking, and other harmful forms of communication that are meant to bully your partner into your way of thinking.

Examples of contempt are:

“It’s like I’m talking to a child.”

“How could you be so stupid?”

“You’re an idiot.”

You’re on the defense

While it’s a natural response to criticism, defensiveness signals to your partner that their concerns don’t matter. Especially when being defensive is your go-to response to any request or bid that your partner makes, it comes off as self-centered.

Let’s assume your partner asked why you haven’t mowed the lawn yet. Examples of defensive responses could be:

“Why are you nagging me about the lawn? You know I have a million things to do.”

“I said I’d get to it. Leave me alone.”

“Oh, like how you were supposed to vacuum the living room yesterday?”

You check out

As opposed to hurling insults or making personal digs, you can swing in the opposite direction and simply shut down. The Gottmans call this “stonewalling” and it takes many forms—one of which is going silent. While it can be a natural response to feeling physiologically flooded, you’re reluctant to engage with your partner, which also means you’re resistant to any repairs.

An example of this when you’re arguing with your partner and they stop talking. They stop looking at you and they stop responding. They seem eager to end the conversation and move on to something else (or move away). This shutting down shuts the other person out and effectively hurts the connection between you.
