Ughhh just had a fight with husband

It started as one thing and ballooned into a big fight, we never fight so this was terribly upsetting. He punched a hole in the door and I threatened to leave with our son. We talked it out eventually but I still feel terrible. I'm sitting out on the couch not wanting to come to bed even though hes asleep. It's just the worst, fighting with your partner. Especially when you have a baby.
