If after discussing your divorce she sees that you're happy about it, it's going to make her think you don't care at all. I didn't read your first thread, but I saw your post about not getting into arguments. Maybe she thought you wanted to not be married to her. Maybe she only brought up the divorce to see if you cared about her at all. It seems like you've given up. Only 4 months in.
I know this website is all about not pursuing the WAW, but if you never really pursued, or really expressed your feelings, or showed her love, now might be the time. At the very least don't go out and throw a party celebrating that she's gone.
So, the question is... what do you want?
Honestly, after detaching I really don't know what I want. She is not "joking" about getting a D. Whether she really knows what a D is remains to be seen. I've tried the pursuit - talks about M/R, going on dates, etc... failed. Pursuit via my own experience does not work. To separate expressing my feelings and show her love from pursuing her I think is just about impossible.
I don't plan to intentionally or unintentionally throw the D in her face. She is already convinced my facebook comment was about her and I did send her a low pressure text which didn't aid my cause.
If somehow this whole D is her way of reaching out for help, that is completely the wrong way to go. She can blame herself for that when this is over.
