Some info and a question for the BS

I don't figure many of the betrayed spouses who frequent this Board would exhibit the behavior you are questioning.

Your affair partner's wife has a mental illness and so her psychiatrist might have the answers for you...knowing how her illness works.

Clarity

I agree with Clarity, most of us here probably don't have Narcissistic Personality disorder. From what I understand people with that disorder don't do things that make sense, at least not to the rest of us, their world is all their own. We just gave some general reasons why the average BS might stay. She is not average. From what you describe there is no way to know what she will do or why she does the things she does.

I wish all of you the best in getting on with your life, whatever you all decide. It sounds like a difficult situation for all involved, especially the kids. Stay safe.
