So last night me and my boyfriend went to a friend's house for drinks her husband went to bed as he was tired, I went out for a cigarette and through the window I saw them dancing and hugging and being quite flirty, I decided it was time to leave so we got in the car and I got very upset and angry trying to speak to him about it in the car I was actually shouting at him at one point. He pulled the hand break grabbed the wheel and put us into a hedge, then he hit me in the face he busted my nose and it started to bleed we got home eventually and he was so drunk he squared up to me saying so what now are you scared of me? I told him to go to bed and I slept downstairs. This morning he doesn't even remember what happened my nose is cut and face is sore and I have no idea how bad the damage is to my car. So here's my question but I probably know the answer already what do I do now?
