I cheated on my girlfriend and I want her back in my life?

you have a tough situation. but the good thing is your ex still talks to you and from what she is telling you, she is actually givin you the opportunity to redeem yourself and prove to her that you are sorry and that she is the one you love and want to be with. I would suggest you keep talking to her and tell her about your feelings and you will come up with ways to show her with actions that she is the love of your life. You should consider yourself lucky that she is willing to give you an opportunity to prove yourself to her, apparently she loves you very much and is willing to forgive you. If I were you, I would do anything in my power to make her feel important and get her back. Good luck.
