My boyfriend yells at me alot...?

Ok so iv been with this guy for almost 3 years. I cheated on him two years ago I apologized and we worked all of that out. Randomly though he will pick fights with me and call me names like slut and says he wished I was dead.... the other night he screamed at me and I was crying hysterically. He tells me i should fear him and he has to watch me at all times because he doesnt trust me to go anywhere.... I dont leave or talk to anyone for fear he would hurt me.... he tells me I deserve all I get because I cheated once... Do I? please answer me back
