Welcome to divorcebusting.com...officially! While it is easy to jump in and judge your wife's situation as MLC/depression, etc.....what it stops you from doing right away is looking at your patterns of interaction.
The best way to affect someone else's behavior is by changing your own. It doesn't mean things are your fault....but it can become a 'wait for her to come out of it game', or a moral judgment that halts you, if you start out looking at it as an MLC problem.
Why not work the Divorce Remedy Steps.....look at what you might be able to change in your own interactions to affect her behavior. You can become the solution!
Since you are brand new here, I'd like to encourage you to post in newcomers. We are here to help you.
The post that Cadet makes welcoming people to MLC does kind of assume that someone has read DR or DB so I must agree with DBMOD that you need to as a minimum read Divorce Remedy before you do any of the homework assignments.
You must start with a beginners mind, a basic tenet of what MWD states.
