I believe that if something did happen and even if it didn't then she should be the one remorseful and try and win back that trust and love. When a cheater or may have cheated doesn't do the things to make it better then what do we have to build our trust again. I don't think its a question as much as it's up to them. Making someone feel better about trusting your spouse then it starts with the cheater or may have cheated. We need that extra security at a time when we are vulnerable to our thoughts.
