Well, first off, girls hate it when you are creepy and stare at them and flirt with other girls, so don't. Act confident and cool, but be nice when she talks to you and don't act desperate at all - it's a horribly unattractive quality. An apology for flirting with other girls when you were with her is a good start as well.

The best advice is to let her be

Go about doing your normal daily routine. Flirt with any girl you want. Have fun. Do anything you want. But if your focus on doing what it takes to win her back, it won't work. Or she would just do it out of pity sake.

Live your life like you don't need her. That will either attract her back to you for being what you are, and what she is attracted too, or you will find someone else that means more to you then your ex did.

Are you in school too?
