Seriously. She bolted your first date to go visit some other guy. I don't think she's fully "recovered". Run from that. Even if you dig her & try to make it work, there will always be the knowlege of her past, & that will give you a constant nagging doubt that will eventually make you crazy.

Thank her for her time, honesty, wish her luck, & move on.

Must be that jumbly-wumbly thing happening again.
