@acp,
Sorry, I have to leave you where I found you. Only you can answer that question, because only you know yourself well enough to answer - or at least you should. If I were seriously interested in her, I think I would have to back away from the whole thing. If I just thought of her as a casual, sometimes playmate, I could go with it. In other words, I would avoid any emotional envolvement. Understand, I'm not saying anything bad about the girl; the two of you may just be incompatible, at least at this time, and trying to change people is an exercise in frustration.
That's what I
think I would do. I am not you, and this is totally subjective.
