Now my question is if the wayward wife has another man. And we have to treat her as if we were her boyfrien
Where on earth did you get that idea? Was it from me asking what you would have done if you weren't M and discovered she was two-timing you? If so, I hope I answered your question in my previous post.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
