Sounds like it just wasn't meant to be. I would forget about her and move on. Lots of nice girls out there and you will find a great match. I wouldn't bother with this other girl as she sounds shallow to me. Get out there and find the right girl for you! She's out there, you just have to look!
just ignore her.... even I dated a boy and he left me. They're all born brats, so just ignore them and we can do nothing else except moving on...
Just forget her and concentrate on life! :)
She's probably just embarrassed to be around you, or she's angry. I mean, she just broke up with you. Which girl wouldn't be embarrassed to talk to there ex's.
