My W is in the same place as yours, except she already HAS filed for D. It sucks, but I am starting to get over it and putting together my game plan as to how to go about various aspects of the D. I have GAL and W seems to be getting more stressed out.
All or her grand plans are imploding around her and she is going to have to accept the "facts" at some point and come out of her fantasy world. I'm through caving in and being afraid of her reactions. Now, I just do what I want to do and don't care what she wants or thinks. It is a better place to be.
Once you start maiking the decisions, doing what you want and pushing this thing along, she may change her tune. Time and patience.
