Is this a friend worth having? Am I wasting my time with her? Please help me, 10 points best answer?

Well she might have VERY low self asteem (maybe due to her weight) and this "ricky" guy knows that and he will continue to play with her feelings until he moves on. Unfortunatly you and your friends have done pretty much all you can do. Just take into consideration how you would feel if it was you in this situation. And try and just be there for her and let her know your there. Also her thinking is prob messed up right now she may not see it and not understand why you guys are just being mean and not wanting her to be happy. So you will prob just have to be the bigger person and back off a little but still be there for her when they split for good. Sometimes people have to learn there lesson the hard way.
