Idk be honest about what you feel to her. To me that just sounds messed up, but I would make sure she's not playing with your feelings, cause I hate when people do that to me >.< I hope it works out for you, that sounds confusing! I'm here for you if you need me :3
I think you should ask her for time so you can think about it. You need to think about what you want as an independent person, rather than thinking as someone in a relationship. Once you know what you want and how you feel, then you should make your decision. You should take all the time you need and not feel bad about how long it takes. You deserve so much more than someone who appears to be playing with your emotions.(You don't have to do this, it's just what I would do)
