A nice honest report creed. I think this one is gonna be hard to reactivate. If anything it seems the attraction was lost when you were walking with her. She walked on whithout saying goodbye for a reason, as with not saving your number. If I were you I'd forget this one and just get yourself out and grab some more numbers. Good work getting the close, and refusing facebook was a nice manovre... taking what you want!

The more hot girl's numbers you get the more you'll learn what to do about each dilema, as your comfort grows with every encounter. It wasn't by chance that you were gelling with her initially. A girl's attraction changes fast, it can be there, then gone as your behaviour or attitude changes (nerves and uncomfortableness is a part of this). Just chill and try to enjoy each future interaction you have.
