Glad to see you keeping up the good fight. I'm not sure where to lead you other than listen inside and do what is right. I think W is a little surprised how I have dropped the rope and haven't turned into an sniveling heap. Right now I have left it up to someone higher. If things turn around, great, if not, I've done what I could.
May I suggest getting back to spiritual and marital basics. Do the simple stuff and focus on your own growth and problems. Enjoy the simple stuff and don't sweat what you can't control.
It's kind of weird right now, it's feels like when you leave for college or any other major thing in life. You know life as you know it is going to change, some challenge are going to happen, but things will get better eventually. I think most people don't realize that a M is as much for the kids as it is for each other. W is taking it away from all of it, it will be devastating. In the long run I think it's going to hurt her the most. Oh how fooled we get every once in awhile.
