That is exactly what I told my WW Sandi. Yes she was shocked, but she absolutely refused to change her ways. Instead she just got extremely judgmental and critical of everything I do.
I was stunned that my H would not want to be friends with me, but I did not change my ways. I mean, he's just an easy-going nice guy! It was hard to imagine him not being my friend after leaving him for another man.
I did not change my ways, either, until later when I decided to do the right thing.

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!
