If she is wayward, she will place male friendships over her own H and M. The fact that she does not want a relationship where both of you can be transparent and not have secrets........is very telling, IMHO.
I can just tell you how a wayward wife would probably react to what you said in the previous post. If she is unwilling to cooperate and do what is needed to save the M, you won't be able to talk her into doing the things you stated above. You are still wanting to use words to fix things, and although I believe I understand what you are saying to her.......I just doubt she will heed to what you tell her.
As long as she wants to have private communication with the opposite sex and keep secrets from her H........I think your chances of success are unlikely. As long as she can say that's not what she wants.......and continues with the old behavior.......she isn't faced (or concerned) with the consequences of what doesn't work in a good MR.
Have you considered calling the Divorce Busting coaches?
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!
