I feel like I brought this all on myself and now I don’t know what to do?

My bf wanted to try new stuff and i agreed to try but then I didn’t like it. So I told him and at first he was really angry but then he apologised and said that he wouldn’t do it again and that he felt really bad, even started crying about it but it’s been a day since it happened and now he’s just laughing about it saying stuff like ‘ you so overreacted ’ and I guess it really upsets me because it’s been on my mind so much since it happened it’s not the first time he’s done stuff I don’t like like grabbing my wrists or choking me in arguments and last year he pushed me to the floor while pregnant and even though we have moved on from that he seems to have completely ‘forgotten’ about all the times he’s hurt me man, I’m just looking for someone to tell me what to do cause I’m lost :/
