Anne was kinda of a creep.

Agree, none of the three main characters were likeable by the end but that's teenagers for you. But the film wanted you to feel for Anne, but I just couldn't by the end what she did to Sasha was pretty scummy even if Sasha was a title bitch to Anne and blew her off cause she was afraid of coming out of the closet. That's why the end doesn't really hit for me like it could have if Anne was somewhat likeable.
