Girls, I need your area of expertise! What's your opinion on her?

If she really meant what she said, she wouldn't have left it for a whole month after saying it. In my opinion I think she's messing with your feelings. She's got her life back with her 'boyfriend and car' and I think she's torn between wanting you and this other guy. But do you really want someone who you think could leave you for months on end without a word? I believe she's sorry, but I don't think her behaviour will change so if I were you I'd move on and find an honest, respectable girl.
