I have a friend that is in her early 30's, she recently became engaged to a man she has known a few years, but supposedly only dated for the last year. The problem is she caught this man in bed with another woman and knows that he had an affair with his best friend's mom. He tells her he loves her and he has changed. He has had many girl friends in the past, from what I hear he was having sex with my friend, his best friends mom and the other young woman all the time telling then all they were his one and only. My friend knows better now, but she still has agreed to marry him. Nothing I say will convince her other wise what am I to do?
