TL;DR. Stonewalling is when one partner shuts down in the middle of conflict, going silent or answering in single words, and it usually starts in the body. Gottman's research found that once heart rate climbs past about 100 beats per minute, it becomes very hard to take in what a partner is saying. The 20-minute rule gives the body time to settle, but it only works if you come back to the conversation. For many couples, the shutdown is also part of a pursue-withdraw cycle, where one partner's pushing and the other's silence keep feeding each other.
If you have been on the receiving end of stonewalling, you know how it goes. You are trying to talk about something hard, and the person across from you slowly stops engaging. Their face goes blank, their answers shrink to one word or none, and they look past you instead of at you. The harder you push, the further away they get.
If you have been the one stonewalling, you know it from the other side. You can hear your partner talking, but the words stop making sense. Your chest is tight, your mind goes blank, and the only thing that feels bearable is waiting for the conversation to end.
Both partners are describing the same event from different seats. Stonewalling is the most misread of Gottman's Four Horsemen, and understanding what is happening in the body changes how you respond to it.
What is stonewalling?
Stonewalling is when one partner withdraws from a conflict conversation while still physically in the room. The signs are usually visible: a blank face, little eye contact, single-word answers, turning to a phone, or leaving without saying when you will be back. John Gottman includes it in his Four Horsemen, the communication patterns his research ties to relationships breaking down, along with criticism, contempt, and defensiveness.
Most people read stonewalling as a choice. "He shuts down because he doesn't care." "She gives me the silent treatment to punish me." In most cases we see, the partner who stonewalls is overwhelmed rather than indifferent, and their body has moved into a state where staying in the conversation feels impossible.
What is happening in the body
The Gottman Institute describes stonewalling as a response to being physiologically flooded, with a faster heart rate, stress hormones moving through the bloodstream, and a fight-or-flight response. Gottman's early lab studies with Robert Levenson measured couples' physiological responses during conflict conversations, tracking the body and the conversation at the same time.
In Gottman's framing, once your heart rate goes above about 100 beats per minute, you won't be able to take in what your partner is trying to tell you. The parts of you that handle listening and choosing your words carefully become hard to access, while the part that watches for threat stays switched on.
There is also a gender pattern in the research. According to the Gottman Institute, 85% of the stonewallers studied in Gottman's Love Lab were men. Anyone can stonewall, though, and we see it in same-sex couples and in relationships where the woman is the one who shuts down. Knowing the physiology helps couples stop reading it as a gender trait or a character trait.
Why pushing to keep talking backfires
When one partner is flooded, continuing the conversation tends to go one of two ways. The flooded partner says something sharp they regret, or they shut down further because more pressure registers as more threat. Either way, the conversation goes backward.
The partner who is still talking often experiences this as "they won't talk to me" and pushes harder, which floods the other partner more, which leads to more shutdown. Neither person is choosing this loop, and most couples eventually figure out that staying in the room isn't working, but few have been given a structured alternative.
The 20-minute rule
The Gottman Institute recommends a break of at least 20 minutes when someone is flooded, because that is about how long it takes the body to calm down. Twenty minutes of stewing or mentally rehearsing the argument doesn't count. The break needs to be spent on something that lets your body settle.
In couples therapy, the 20-minute rule has four parts:
- Notice flooding in yourself or your partner. Signs include a blank face, one-word answers, a tight chest, the urge to leave the room, or losing track of what was just said. Either partner can call it.
- Say it out loud and agree on a return time. "I'm flooded. I need 20 minutes. Let's come back to this at 8:15."
- Take the break and use it to calm down. Take a walk, take a shower, put on music, or read something unrelated. Scrolling, drinking, or rehearsing your side of the argument tends to keep the stress response going.
- Come back at the agreed time. This step is what separates a healthy time-out from stonewalling.
What helps you calm down during the break
Gottman calls the antidote to stonewalling physiological self-soothing, which means doing things that bring your heart rate back down so you can return to the conversation able to listen. What works varies from person to person, and most people do well with some mix of:
- Movement that uses big muscle groups, like a brisk walk or a few flights of stairs
- Slow breathing with an exhale longer than the inhale
- Cold water on your face or hands
- A different room, headphones, or closing your eyes for a few minutes
- One absorbing activity, like a song you know well, a stretch, or a small chore
What tends not to help, even though it can feel productive: replaying the fight, drafting the perfect comeback, or sitting in the same spot with the same tension and telling yourself to calm down.
The goal is to get your body back to a state where the original conversation can happen, not to push the feelings away.
Coming back is the hard part
In our experience, the 20-minute rule most often breaks down at the return. The flooded partner takes the break, their body settles, and the conversation never gets picked back up, so the break turns into a disappearance.
When that keeps happening, the other partner stops trusting time-outs. "I need a break" starts to sound like a stall, so they stop offering breaks and push through instead, which means more flooding and more shutdown. Over months and years, couples end up in a version of the cycle that feels like it has no way out.
In our work with couples, a healthy time-out is a break that comes back. If you can't reliably return to the conversation within a few hours, the break by itself won't solve the problem, and that is a good time to bring it into therapy.
What's underneath the shutdown
Michelle's couples work is EFT-informed, and in Emotionally Focused Therapy terms, the partner who stonewalls is often the withdrawer in a pursue-withdraw cycle. Withdrawing can look like not caring from the outside, but from the inside it usually comes with a fear like "I'm going to say the wrong thing and make this worse," or "Nothing I do is ever enough, so I'll stop trying." Going silent protects the relationship from a fight the withdrawer expects to lose.
The pursuing partner has a fear of their own, usually closer to "I don't matter to you" or "I'm losing you." Their pushing is an attempt to reconnect, but to a flooded partner it sounds like more pressure, and each person's move confirms the other's fear. Our post on why couples keep having the same fight walks through that loop in detail.
In EFT-informed sessions, Michelle slows that loop down so the withdrawing partner can describe what is happening inside them while it is happening ("I'm going blank right now because I'm scared of getting this wrong"), and the pursuing partner can hear that silence as fear instead of rejection. Once the silence has words attached, the pursuing partner often has less reason to push, which gives the withdrawing partner more room to stay.
When stonewalling becomes a pattern
Everyone floods sometimes, and almost every couple has had a stonewalling moment. What matters is whether stonewalling has become the usual way conflict ends. Signs that it has:
- Most hard conversations end with one partner checked out rather than with any resolution
- One partner has stopped bringing up hard topics because they expect to be met with silence
- One partner is keeping a private list of grievances that never get discussed
- Both of you feel lonely inside the relationship, even on days when nothing is obviously wrong
When stonewalling is built into how you fight, the 20-minute rule helps but rarely changes the pattern by itself. Couples therapy can help you map the cycle, understand what each of you is protecting, and practice a different way through conflict. The Gottman Method works with the Four Horsemen and their antidotes directly, while Emotionally Focused Therapy works with the attachment fears that drive the pursue-withdraw cycle, and we draw on both.
Some silence is something other than flooding. If a partner uses silence on purpose to punish, control, or frighten you, that is a different situation, and a therapist or the National Domestic Violence Hotline (1-800-799-7233) can help you sort out what is happening and stay safe.
Getting help
If you recognize your relationship in this, keep in mind that the shutdown is a body-level response that has been reinforced over time, and a body can learn a different response with practice. Many couples can start the 20-minute rule on their own, while the patterns underneath it tend to change faster with a couples therapist helping both of you slow down.

Common questions
- What is stonewalling in a relationship?
- Stonewalling is when one partner shuts down during conflict by going silent, looking away, or giving one-word answers until the conversation stops. It is one of the Four Horsemen in John Gottman's research, and it usually happens when that partner is physiologically flooded, with a racing heart and stress hormones that make it hard to listen or respond.
- What is the 20-minute rule?
- The 20-minute rule means taking a break of at least 20 minutes when either partner is flooded, then coming back to the conversation at a time you agree on. The Gottman Institute recommends at least 20 minutes because that is about how long the body needs to calm down, and the break works best when you spend it doing something soothing rather than replaying the argument.
- How should you respond when your partner stonewalls you?
- Call a break instead of pushing harder. Say that the conversation has stopped working, suggest 20 minutes apart, and agree on when you will pick it back up. Pushing a flooded partner to keep talking usually leads to more shutdown, while a break with a set return time gives you both a better chance of finishing the conversation.
- Is stonewalling emotional abuse?
- Most stonewalling is a flooded nervous system shutting down, not a deliberate tactic. Silence used on purpose to punish, control, or frighten a partner is different. If that is happening in your relationship, a therapist can help you sort it out, and the National Domestic Violence Hotline is available at 1-800-799-7233.
- Do men stonewall more than women?
- In John Gottman's research, 85% of the stonewallers studied in his Love Lab were men. Anyone can stonewall, though, and the pattern shows up in same-sex couples and in relationships where the woman is the one who shuts down.
