Glad to hear that the fundraiser went really well and it was as Zew said drama-free. Score 1 for Nit.
I want to remind you to send a very short and simple "Merry Christmas" text to W. You mused that you felt that W isn't feeling the consequence of her choices. She probably is to a certain extent. My sense is that she will most probably feel them after The D is final and all of the financials settled.
Let me share a bit about my own experience. As you may know, I had my own MLC and dropped the bomb on Ms. Wonka's birthday (yeah, I won the Spouse of the Year award :/). I did face the consequences of my choice such as: 1) Ms. Wonka left me for OW 2) Our house got sold 3) I suffered a bit financially due to the split 4) I berate myself t times for the BD and the subsequent fallout.
Finally, a D is just a proclamation that you're no longer married from a legal standpoint. As you can read in the forums, people DO reconcile even long after a divorce. There's always hope.
