I dislike my mom's boyfriend...alot. Should I move out?

I would talk to relatives about this, no one should have to go through that. I think that you should have a nice long talk with your mom and say that if you don't either get rid of him or change something i am leaving. She should decide to change things since you are her son. If that doesn't work put up a video camera and next time her boyfriend hurts you, you will have it on tape. It might be a little spendy but it would be worth it. You can then tell your mom that you think she should pay for the camera because she forced you into it. If even this does not work than you need to talk to relatives. He may seriously hurt you than put the blame on you. I hope this helps.
