No, I would not suggest going dark at the moment, but I do suggest you read the 37 rules, as a guide to get you started in how to interact with her.

At the bottom of that first page of rules, is a link to a series of threads about the wayward wife. It could save you valuable time, hopefully, if you will run through those, too. I think you will see how you need to take a much stronger stand, if you want this WW to return.

I have read many of the same descriptions about wives on this board. She is absolutely his world. So much, in fact, that he has become co-dependent on that MR. All his free time is with her. His old friends kind of fell behind, and he gave up most his hobbies/interests b/c now it's all about his family.

A lot of the H's who have a WW fall into the "nice-guy" type of men. One thing that will not work to win back the heart of a WW is your nice-guy way. You cannot nice her back.
Hope you'll read those links.

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!
