My boyfriends mom hates me and I hate her.

I’ve been with my boyfriend, since I was 14, and I’ll be 19 next month. And his mother, step-father and brother absolutly hate me. His parents moved out of the state shortly after him and I started dating. He had to move out of the state to finish his last year of high school, after he graduated he moved back and lived with my parents and I for 2 1/2 years. After I graduated, I moved a thousand miles away with him to stay with him and his parents. I cheated on him a year ago because I couldn’t take him and his family any more. His step-father is very abusive both mentally and physically, his brother is an ungrateful, immature child who has an anger problem, and his mother is just a b*. She never liked me from day one. And recently she threw me out of the house because my boyfriend and his brother were arguing over my x-box and I told his brother to grab it out of his room, since it was mine. Well, his brother put his hands on me and neadless to say it’s my fault why they argued because according to her I had no right to say anything. His mother is constantly talking badly about me, and I don’t know what to do. I plan on having children someday but how would that be when I hate my boyfriends mother and she hates me. I won’t even go back to their house because of how crazy she is and her husband has been brought up on rape charges. The whole family is just a mess. What should I do?? Should I try and make things work with my boyfriend and I or should I just call it quits?? He didn’t even stick up for me when his mother called me a bunch of rude and inappropiate things, and many other, including threatning me after I made the desicion to leave her house…
