My bf has been living with me for a few months. We were at it in bed and he started slapping my ass while going faster. We never discussed anything like this before and I kind of froze and didn't do anything. It was hurting. Then he turned me over and out of nowhere slapped me in the face and it stung and he kept going.

I freaked out. I got off the bed and he said "what" and went up to me. I told him to get out and slapped him across his face and pushed him towards the door. He started arguing with me but I just told him that we are done. He has been blowing up my phone saying that he thought it was fine since I "was going along with it" and that I'm throwing our relationship away over a misunderstanding.

AITA?
