Please Help My hearts been broken what do i do? read all details please i know its lil long but its easy read?

This is a really hard subject. It sounds to me like she did like you and she may still like you but she is trying to see if she likes this rob guy better. I think you should try to be friends with her and see where the relationship goes. Prove to her that you won't ever turn back into "that guy." If you stop talking to her you are just proving to her that you haven't changed. I know it may be hard but you can get through this. Who knows she might break up with him and figure out that you are the right guy.
