Look man, here is what she is doing-
She really wants to be around you because she misses the connection. She wants you to be there badly, but only on her terms. (This btw, is exactly what my ex girfriend did) She thinks that if she can have you as her best friend she will feel better about everything. She still wants you for the emotional support.
So here is what you need to do. Make it perfectly clear that you don't just want to be friends. You want it to be more than that. So don't be a cuddle whore (being there for her when she wants it emotionally) if you aren't getting the same back in return. Stay out of friend zone as much as possible. If she pulls the "I just want to be friends with you" line, tell her straight up that you are not ok with it. Don't be an asshole, but make sure she knows what you want.
