betraying my abusive ex

After 2 and a half years with my ex i finally left. While i was with him i wasn't allowed to hang out with friends and if i ever even talked to another guy then i was called a slut and if it pissed him off enough then I'd get pushed around a little till he knew he had my attention.... I just broke it off and since then im still scared to even have another guy look at me. I feel like im betraying him and he's going to get mad at me.
