Is this normal behaviour? When we argue he always defaults to "I've had enough of this, I'm leaving". He maintains this for several hours sometimes days after the argument. I suggest talking, he responds with "what's the point, there's nothing to talk about". Eventually he calms and admits he overreacted and he won't leave. We have a 10 month old baby. Every time he does it I'm just on edge wondering when he's going to do it again.
