Two things I want to say about friends. First is that what friends think about your M (good or bad) is based on what they can see and/or hear. None of them are behind the closed doors to your most private, intimate, and daily lives as a couple.
Second, the WW usually gets new friends b/c she wants to connect with people like minded to her. They will pull away from family and friends that are part of her old life that she no longer wants, and/or who do not support her waywardness.
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!
