I just got done reading your thread and I think you really buried the lead in this story.

At first, I was sucked in by your W's "plight" at being a "neglected" spouse, but then you reveal that your wayward W is actually a therapist! That giant sucking sound you now hear is all of the sympathy that I had for her heading south.....

I can fully understand why your parents can't stand her now.

Also, you mention that you have something on OM that could blow him out of the water. I think I would wonder why I am still interested in someone who is still interested in a crumb like the OM.

Send the letter.
