can't get over him.

It's been a month since I found out my bf was cheating on me .. he's with that girl and he tells me he still loves me and all this other crap and we ended being on good terms as friends but he got mad at the fact that a guy friend gave me a hug so now I'm a " hoe " and well he goes around saying shit abt me.. I want to get over him, I really do. He did so much hurt to me. I spent 1 year and 4 months respecting him , giving him everything he's wanted, did everything for him just so he can go cheat on me.. I'm still so hurt . I go out with my friends to dances and stuff but I still think abt him. I cry almost all the time. This is gonna sound so bad but I wanted to forget him so bad that I had sex with this guy I have known for a long time and he's amazing but Idk. It's confusing.. I don't know how to get over him. I've blocked him & everything but his memory still comes to my head .. all the good times we have had and now I wanna just cry seeing them at school kissing and how everything he did for me , he does to her. I just can't take it, I hate both of them.
