There’re a few way if your question is - “Help me reconcile with my ex-girlfriend“. You still have hopes:

One thing to remember when you want to get your girlfriend back. Make it easy for her to get in touch with you, but don’t push her into it. Ringing her every night is not going to help. If you’ve done everything above you have shown her you are sorry and you have somehow got the correct version of events to her. If she wants to come back she will, and if she does don’t expect an apology from her for her misunderstanding the situation that originally caused the break up. Just let her know how happy you are to have her back and how much you are going to enjoy being together from now on.
