"Great things happen to those who wait" This quote really fits your situation mate, if you wait for quite a sum or period of time, then she will come to you.
Do you play any sports? Or do anything extra-curricular?
The best advice is to leave it go, she will come back to you, just go back to the way you were with her before you guys dated, and she will fall for you again, but do not show her you want her back, just be who you were, basically... Pretty simple
Well girls are mostly satisfied with hot guys but not all of them are they mostly like guys who are smart,caring,comforting,nice and guys who don't rush a relationship if you have been in a relationship for only a week and you surprise her by kissing her in the lips she would probably slap you and break up with you give her some flowers or chocolates and apologize and maybe she won't be so angry at you even though i don't have a girl yet i know LOTTTSSS of stuff! Trust me Yahoo has it's uses... and so do watching videos on youtube,and reading random books
