I'm sorry, and I'm sorry you find yourself here. Most of us here know what you mean by that shocked feeling. YOur W seems to be moving amazingly fast with the D papers, but the D process is just starting for you so don't panic.
Have you read the MLC Resources thread at the top of this forum? It is extremely informative.
There are many different views here on whether or not you should actively fight and stall the D. I'm of the view that you can't stop it, but that you can slow it down to a pace that lets you process it, and try to make the MLCer do 100% of the work. Sounds like your W is already doing that. We call those freight-train MLCers. My XH was one, which is why I wanted to be sure to post to you.
Take some deep breaths, take good care of yourself physically, and hold on. If you are getting papers already, you really need to consult an attorney. You can let the L handle it all, and you can instruct the L to go at your pace...just because your W wants to "Move on" doesn't mean you have to move on at her pace!
I hope this made sense, it is the middle of the night. Good luck and keep posting.
