I just assume that if she wanted to stop the marriage counseling she would speak up. Is that assumption incorrect?
I would think so.
It's good that the family experience positive results from your changes. Your W has legitimate concerns about the changes reverting back to old habits, b/c it is very difficult for adults to stick to big changes after they become comfortable and aren't threatened to change. That's why it has to be for "your" benifit.....and not based on wanting to be with your W. I don't think you are willing to go that route. I'm concerned that you feel that changing would be important if you didn't keep her.
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!
