Diagnose heartache please......what do I do?

hun, I think she just doesn't like you like that. but if you really want to be her friend then the next time at tennis, just tell her that you don't want it to be akward anymore and that you just like her as a friend and that you really hope that you guys can get to know each other and become friends. if it's meant to be then it will work out from there. if not, then she just isn't in to you...sorry. but if she just has 'flings' then it's not even worth it! why would u just wanna hook up with someone if u know that it's not gonna last??? Good luck!!!!♥
