How to get my ex-girlfriend back?

Well when you do bickering things girls think they are augments so you need to let her know you were wrong for doing it and you are sorry and will never do it again and that you can't live without her tell her exactly how you feel and she means the world to you i know how you feel because my girlfriend broke up with me about two weeks ago. and i feel horrible because she is all you think about so i hope things turn out for the better.
