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...
