You clearly have done your search much like I did. When the DR book arrives in the mail your going have more to think about. The thing that I have observed, even in the DR book that dealing with the WS takes patience. What you will find in the book will at times deviate from what I have seen on this forum. Your line of thinking is what's in the DR book. So I can see why you might be resistant to some of the advice being given.
At the end of the day, its about figuring out what works in your situation. You may GAL and do 180s, which might work. Then you may find that it doesn't get the job done. And you will find yourself having to use harsher methods as has been suggested to you. Stick with what your doing now, but GAL. Do wait on her. Considering that she said that she had no issue with you. Then you already are the better man. W just needs a reminder.
Also LH19, LiM and leahsue if you all could take a look at my sitch under "Wife wants to leave marriage." Let me know if you have any advice.
