There has actually been some recent activity in this regard on an old thread:
Life after Divorce / Separation
The thread itself is well over a year old, but it was revived last month with some folks sharing updates and developments...accompanied by some noise about an informal get-together (or a series of them).
Unfortunately it's quieted down in the last couple weeks, and I don't know if anybody's actually managed to set anything up; if so I obviously didn't hear about it (and shame on me I haven't really taken any initiative myself) but it's something I would still be interested in too.
I will cross-link your inquiry into that thread and see if that revives any activity among people with better heads for organization than me

!
Hang in there! When I was in the middle of the sh*t this time last year it helped me a lot to cruise around on EF and find out how many people have been through shockingly similar nightmares and survived. You're not alone.
All best,
Ed
