Partner and I were having an argument whilst I was cleaning out the bedroom.
Things started to get very heated and I could tell nothing was going to get resolved when we were both pissed off. So, I told DP to leave the room several times and said that we'll talk when we're both calmer. DP refused every time I told him to go downstairs. I eventually told DP that I was very close to losing my temper, and that he needed to leave before I screamed. Again, he refused and stood in the doorway. I then just slammed the door over.
He punched the door and yelled at me that I almost broke his fingers. I said I was sorry and that I genuinely didn't know his fingers were in the door.
I know that people will say that I should have walked away to another room, but I know he would have followed me and things would have escalated. He has form for doing this when we argue, I'll ask him to leave the situation and he'll refuse, or I'll try to leave, and he'll follow me.
