She found out about my secrets and my past... she didn't even answer any of my calls or texts, she didn't even listen to me ,

How did she find out?

How old are you both?

How long have you been together?

What kinds of secrets did you have that was bad enough to cause this break up?

Why didn't you share your secrets with her ?

When I found out about my Gf's past I felt the same as your Gf does now. It is understandable . Think how she feels and just try to stick with her is about all what I can say?

What about your past prompted her to stop talking to you. Some people, in relationships, can't handle their partners past. That is not your fault. If you have a chance to explain yourself, take it, but if she can not deal with whatever you did in the past, move on.

Great questions to answer.
