Is taking space after conflict the same as silent treatment?

No. Taking space is: "I'm upset and need time to think. I'll be back to discuss this tomorrow." Silent treatment is: refusing to speak, communicate, or engage—indefinitely—as punishment. One is self-care; the other is control.

How long is it okay to not talk after a fight?

Minutes to hours is fine—cool down, process, return when calmer. Days without communication? That's concerning. A week? That's silent treatment. Healthy relationships resume connection, even if the issue isn't resolved. Silence used as punishment erodes trust.

How do I know if my partner is using silent treatment intentionally?

Ask: "Are you taking space to cool down, or are you upset with me?" If they say they're just upset, believe them and give space. If they refuse to engage after you've asked for connection repeatedly, that's intentional punishment and a dealbreaker dynamic.
