“He goes silent for days after every fight”

What could be going on

Silent treatment: Fits if the silence feels like a punishment that ends only when you give in or apologise.

Stonewalls in conflict: Shutting down mid-conflict; check whether he goes blank, leaves the room or stops responding.

Emotional flooding: He may be overwhelmed, not punishing; check whether he comes back calmer and willing to talk.

Deactivating strategies: Fits if he copes with upset by switching off feelings and distancing, a common avoidant pattern.

Pursuer-distancer (demand-withdraw): Check whether the more you push to talk, the further he withdraws, and round it goes.

Passive aggression: Could be anger he won't state openly; check for sulking, sighs and pointed silence.
