Sadness

Sasha
I fell for the wrong guy, this guy who I liked, for so long, we grew up in the same neighborhood, and he made me feel good about myself, now when I asked him if he wanted to date me we broke up after a week, of dating. 
I changed my whole body and personality for him. And yet I still love him. 
He's into cheer leaders and that's why I just can't seem to let go of him. What can I do I just feel like I wasted my time. And honestly I never really been in a relationship with no ever. And it hurts having to go over it all with him. 
How can I accept the fact that I'll never be loved by any guy? When the only guy I really liked was him because he wasnt a douchebag like the rest of them???
