When H & I first split, he continually questioned the kids "What did I say about him?" They told him I told them he loved them, and was just lost right now, and needed their support. It enraged him. He WANTED me to bad mouth him. Took some of the guilt off of his shoulders, I suppose.
Later on, he told my DIL, "I don't want you to hate (me)" and she replied "Why should we, she didn't do anything".
