I never wanted the marriage to end and still don't, but it is out of my control. I know I don't need to rush into anything.
I have not read the books, yet. I don't know that I will. Seems like you just need to do your own thing, stop bad behavior, and not be pushy. I interact very briefly with my wife concerning the kids. That is it. For a while, it seemed like she was making excuses to call me. With no contact, she has stopped that too. Although I feel better. My expectations don't get raised. She goes out of her way to avoid me, maybe guilt. I am calm, confident, and positive.
All I do is light a candle at church every Sunday and pray for her happiness. I also pray that this negative event has an overall positive effect (on me, my wife, and my kids).
