It has nothing to do with revenge. Not trying to get him to hate his mother, he already knows she cheated. But in my family we consider it highly disrespectful to even associate with a man like this under these circumstances. Nothing to do with revenge, but it's a loyalty thing. That's what I have always taught my son. Lile it was taught to me and my siblings by my parents. I want S13 to love his mother, but he also needs to know that her actions are dead wrong. And that you never accept someone like OM.
