Mandy, I am quite sure that he feels regret, and regrets what he did. Unfortunately for your son the vast majority of people will not admit they have done wrong and will continue to live in misery putting on the appearance that they have made the right decision. I find it very interesting that this OW called you. Things must be pretty rough there for her to make such a drastic move. They have been together for over 2 years and she has made no effort in the past and could care less. I mean if she were that concerned about your son, she could stopped him from turning you and the boy out of the house. Mandy, this is an attempt by her to find a way to make things easier on her. If there is no communication between the 2 of them, it won't last.
