She gave all kinds of reasons why my suggestion wouldn't work so I said "I understand, I agree. Good decision"
I am giving you a Nerf 2x4 over your head about agreeing with W's opposition to the deal. Tuff chit that W does not agree with your "suggestion." Better comment would have been: "I am sorry that you think that way." Simplicity at its best is often the most effective method to erect a boundary without being pulled into W's crazy talk.
Since the affair continues and W is now living with the OM. Perhaps can draw a boundary with having daughter interact with the OM. This is tough since she is a toddler and she is entitled to visitation with her mother.
Puppy...come on over here and give CD some guidance on how to bust the affair between his wife and the OM. It seemed to work in your sitch and CD could benefit from your tactics. The challenge is that CD's daughter is not an adult so that would not help at all as it did in your case, Puppy.
