So I’m worried

My boyfriend and I live together and have dated in the past for a long time. We started dating again around October. We started living together in April and it’s been fine. We fight a lot but we also have the sweetest moments. He remembers things I like and he brings me home gifts out of the blue. He does great things for me. But we got in a fight about a month ago and he got red and in my face screaming at me and said “are you trying to get your head knocked off” which scared me. Nothing like that has happened since but tonight he got even more mad and he shoved me. When he did I hardly landed on the dog and slammed my head into the back of the couch. Now I have a migraine, ear ache, and there’s a dip/dent in the back of my head. I don’t know if it’s a concussion because I’ve had one before but I haven’t thrown up. Do you think he will start hitting me if we got into another heated fight? I love him and have NO where to go so I can’t just up and leave right now. I’m not going to sit here and be beat on but he just pushed me while mad.

Please don’t be too dramatic in the comments I just wanna know do y’all think it’s dangerous.
