Mind fuck. Sounds like she just doesn't know what she wants mate, and shes just using you as an option. At the end of the day you are not together so if you keep seeing her and making her feel good she wins.

Sounds daft but you should be punishing her for braking up with you, not rewarding her. You have to ask yourself if you just want to be an option for her. Or if you want to move on. Its a fucking difficult question to come to terms with and its pretty blunt but at the end of the day its a decision you have to make.
