I read that book and watched the movie. But I can't recommend it working with a WAW in an A. It is very pursuing, and pursuit will not work while her heart is closed to you.
You are thinking of doing things that would great.....if the M was healthy. You have to accept the fact that all those sweet little tips you read in how to improve your marriage......just doesn't work on a WAW in an A. It will, however, make things worse.
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!
