RTL - I'm proud of you. I'm not sure you could have handled this any better way. Except the deal with having L so involved. Just my opinion, but I think early on you were more concerned about protecting yourself; rather than protecting the bond (aka M). But it's ok, really.
I'm following along.
1 - KEEP THE RING ON. You must not send any message to her other than you want this marriage back. You are not communicating as you should because of the circumstances ... so you can not allow any doubt of your committment into her mind.
2 - You want to be detached to the point that you are not emotionally slaughtered. But you have to have sympathy for what she is going through.
The real work starts now. Refuse To Lose. Live your screen name.
One thing your W was correct on, the L do not care about the M. They aren't there to keep you together. Give her space and time and stay on course.
What's the goal? And ask yourself over and over - "Are my actions getting me closer or farther from the goal?"
You'll be ok. Get through the next few days and then dig your heels in.
