How do you prove to your girlfriend that there is going to be no more cheating?

Smother her wit love. For example be around her at all times,tell her you love way more than needed,etc.If you dont want to do that much just sit her down and how a serious talk with her that she should trust you and that you promise not to have anything go on with another girl * All I can say is you shouldn't have done it in the first place. It can be sole destroying for a woman. It can make them feel worthless. I have been thru it and unfortunately I wouldn't place my trust in anyone at all. It gets to the point that whatever you say to us, we probably wont believe you. you will have to try damn hard to convince your girlfriend that this wont happen again. Trust is a hard thing to win back once broken. Respect and unfortunately what people think of what you have done may ruin your reputation for further relationships. Dont make it a pattern as so many do.......
