You may not see it as such, but I think your W will see it as you controlling.....if you try to push her to therapy. Even if you present it as a deal, she won't respond willingly. I know you are concerned, but you have to take care of things on your end and not try to work her stuff, too. That is part of the "letting her go", until she sees for herself and wants to reconcile.
It seems like a fine line for many men. It takes a little practice.
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!
