Awww... the problem is you got oneitous over a girl too young to figure out what she wants let alone who she wants to do... Enjoy the fact you enjoyed her company, and and be really light and driveby with her in regards to your life, flirt with cute comments for a while and see how she acts...
I'm going to put her aside, she still has me on her facebook and the only reason i dont delet her is that i really saw a beautiful future together... But life goes on and i cant let it bother me :-)
there could be a number of reasons why this girl has decided to suddenly call it quits. girls are complicated creatures, and it sounds like a similar situation i found myself in about 4 years ago. she sounds confused to me, and you probably made her feel things that scared the shit out of her. my advice? let it go for now, and if something more is meant to be, it'll happen.
