That's a tough one. When a guy ends a relationship its probably because he is done.
Having said that, the first thing you should do is identify how and why the relationship ended. Then look inside yourself and figure out how you contributed to it. That's not to say its entirely your fault, but you want to do is correct inside yourself what he sees as the main factor. Lastly you need to identify what values he holds most dear. Using that you frame your approach. Call him and tell him that you would like to talk to him. Hope for a face to face meeting. But be willing to settle for a phone conversation.
In your conversation, tell him that you have identified what went wrong in the relationship and show him that you know how to correct it.
