regarding my comments to Sandy, my next question is if I confront OM, I'm pretty sure it won't take long for it to get to her and then I'll be dealing with her, And I don't have the script for that one.
And I know I shouldn't do one if not prepared for the other. As you all say, I get ONE chance at this.
My thinking is - when you know and have facts that this is more than the garden variety colleague relationship, go to W with the facts first. "W, I know x, y, and z. It is disrespectful to me and our M. I have decided that I will not tolerate that behavior and if you will not end the inappropriate contact, you will have to leave and I will begin the D process." THEN go to OM and tell him what you told your W and that you want him to stay away from your family.
