My husband was like that, we would argue and then he'd be fine but I'd still be mad. He'd try to talk to me normally but I'd just harrumph and tell him to leave me alone. Then the argument would start again because at that point I was holding onto things according to him lol. Eventually he would apologize and id stop being mad. But that's just the way I am, he was was able to get over it instantly. I think that's just the way people are, nothing to do with bipolar.
