I wouldn't have mentioned the "poacher" comment to W at all. I've never brought up Ms. Wonka's OW....ever. She's nothing to you.
A more firm response would have been along the lines of "what you and OW did was incredibly disrespectful to me. I am stunned by this behavior. I want to be clear here: OW is never to be permitted to be near, around or in the townhouse. If I ever see the OW around again, I will take steps to address it myself. Are we clear?"
When I learned the extent of Ms. Wonka's A, I got very angry and told her in no uncertain terms that the OW was not to be in or near the house. I ended it with a very strong comment that I would take matters in my own hands if I ever saw the OW around the house. Ms. Wonka knew by the tone of my voice that I meant business.
Of course, Ms. Wonka took their rendezvouses elewhere. I really put my foot down on that one particular issue.
