Breakup. NEED ADVICE!!!

Essentially, in May, my boyfriend of eight months broke up with me because he "didn't want to be in a relationship anymore". He told me that he wanted to focus on himself and school, which it hurt but I understood. However, not even three weeks later, he was in a new relationship.

That hurt so much. But just recently I learned that he broke up with me because I wouldn't have sex with him, not because he didn't want to be in a relationship.

I know that I deserve better, but I'm still hurting. Care to give me some advice?
