My two daughters age 17 and 20.. won't speak to me. I left their dad and have started a new life. They don't know why I did it, he has told them that I cheated. I did have an affair, yet it was after I had already made the decision to leave. I was very unhappy for years. I assume they think I am a piece of ****. How do I tell them he was a horrible husband, without belittling him. To their face.
