What to do?

Always go with your gut feeling. I think that once someone has an affair, trust flies right out the window. Without trust there is no way to grow closer to that person. So sometimes people stay with a cheater but never really trust again. Seems like a waste of precious time.

This may sound like a broken record,but I honestly believe a relationship needs open,honest communication for it to have a chance to succeed.Find out WHY the other person feels the need to cheat(or consider the idea of cheating).If the two of you are unable to communicate though,then it is time to look seriously at ehat direction the relationship is heading. By the way,if someone cheats on you,shame on them If they do it again,shame on you.
