I don't know this girl, but from a girl's point of view, I've seen what she's done before.

Some guy comes around, acting like he's the one, saying everything right and you fall for it hook, line, and sinker. She def wouldn't have even listened if she was completely happy with you. The ill will could be her trying to put up a strong front because she is broken-hearted about what happened between you two. And sometimes, in the end she figures out that this new guy just used her and she realizes what she left behind. I've seen this happen to friends. Girls are emotional and you should def really figure out what she wants. She should figure out what she wants too.
I'm in no way says that Jae should take her back, I'm just reading through all this from a girl's propective and seeing that it could be looked at another way.

just my two cents. don't all jump on me at once :happysad:
