I think it really depends on the person, but based on what I have experienced and seen, there is usually so much damage that is done by the MLCer that the children won't have a lot to do with them. My father was terribly mean to all of us when he left my mom and did the things he did. Today, I barely speak to him, he has tried to do some things, but there was just too much hurt to get past. I guess what I am saying is this, when a child feels betrayed by an adult in that way, its very difficult, if not impossible to gain that trust back.
