I don't know what to do...

Maria
My boyfriend and I broke up after s year and a half of being together.. There's been times he's treated me like nothing but CRAP. But I still love him.. I lost my virginity to him and everything else along that line. I'm so attached.. I told myself it was ok we broke up and I was fine, till I see him hitting up other girls like we always does when we break up.. But then that's what makes me what to come back because he's mine.. And I don't want anyone else to have what I had.. How to I get over him? Am I too selfish? I dont know if I should bet for him back..
