My girlfriend

My girlfriend broke up with me but I still like her and I don't know why she doesn't wanna go out anymore I was gonna ask but I didn't.

what should I do

Well first of all, maybe ask her.
or think about why she broke up with you. What did you do that you know you could have done better? admit that to her. She'll appreaciate it.
hope I helped :D x

What the hell are you waiting for??? you better get to asking her espically since you cant seem to know what you did. what ever she has to say try and convience her that you can change but only if necessary.

Move on. You have NO control over someone elses feelings, and actions. She broke up with you because she no longer wanted to be your girlfriend anymore. Teen feelings change from day to day, month to month...who can keep up with them.
