Re: Don't know what to make of anything.
It sounds to me like she is enjoying the attention being given to her by you, while also enjoying the company of her new boyfriend. If this is the case, that is not fair to you or the new boyfriend. It is called "having your cake and eating it too."
However, to truly know why she wants to see you or why she calls you now, all you have to do is ask her. You must realize her intentions in a clear and consise way, in order to spare your feelings. It sounds like you still have a lot of feelings for her, but you can't keep chasing someone who has moved on with someone else.
