Back up, NOW. Stop chasing her. You are giving her the full-court press, no wonder she will not give you an answer. Would you have acted like this when you first met? How would she have reacted?
Stop asking. If she mentions it, great, if not, keep moving. You are taking a possible get together as suddenly she wants to be back together.
You are setting yourself up for hurt with unrealistic expectations.
Relax. Be the confident person you were when you first met. Pursuit is unattractive, especially in a tenuous situation.
