Either way, its time for you to start living a healthy life and setting an example for him....
The FT articles are just a start. Begin collecting lots of interesting stuff, but don't SHARE it with him... shut him out... If he wants to be part of the marriage he has to work for it... if you chase him with the marriage like its a baseball bat he's not going to cooperate with you...
So, start enjoying yourself and your marriage without him.. take the kids out and exclude him... make dinner for you and the kids and don't make him any...
start showing him what divorce is going to feel like...
He can't miss you if you are in his pocket 24 x 7
I feel I've been doing a pretty good job of this - getting my stuff together to go back to school, going places with kids. Some of the other stuff is harder because my 180 would be to always cook dinner - keep the laundry caught up - do more "wife" things... Like I said: I was a depressed person for several years who wasn't much of a wife, I admit it. So now, I feel I kinda have to be the wife to show him what he could have. It's a difficult balance! Obviously he's noticed, but now what? I've been nice as pie but been very careful to detach and not be needy at all. That's the best I know to do right now.
