It appears that you need to move forward with your life. You are correct...there really is nothing left you can do to get your W out of her funk. God knows I've tried with mine. We share the same situation. This is their problem now...time for us to move on buddy. Maybe filing for divorce will snap your wife out of it. Maybe not. If filing doesn't wake them up, I can't think of anything else that will. It is what it is my friend.
