Why People Stonewall

Stonewalling is usually a response to emotional flooding — the feeling of being so overwhelmed during conflict that the nervous system shuts down as a protective mechanism. It's often not a conscious choice to punish; it's a stress response. People who stonewall frequently feel physiologically overwhelmed (elevated heart rate, difficulty thinking clearly) and withdraw to regulate.

That said, the impact on the other person is significant: it signals that the conversation — and by extension, their concerns — don't matter enough to engage with.

What to Do About It

If you stonewall: signal that you need a break rather than just going silent. "I need 20 minutes and then I want to continue this" is fundamentally different from simply shutting down. The goal is to de-escalate without abandoning the conversation entirely.

If your partner stonewalls: pushing harder doesn't help — it usually increases the flooding and extends the shutdown. Agreeing to a defined break and returning to the topic at a calmer moment is more productive than demanding engagement in the moment.
