I know it's a sad thing, and I understand you're still concerned about him and how he's doing. But I think once the dust settles, you'll be relieved that this paperwork is all over and done.
Anything that does or doesn't happen now will be independent of all this financial garbage. (I never understood how people could celebrate finalizing a divorce, but by the time mine was done, I just wanted to have a party to celebrate being done with the HASSLE. Life definitely got better from there on out.)
Now you can focus on getting your own finances in order, you know what you have to work with. It's sad that a marriage has ended but this was over a long time ago. If he wants to resuscitate it it's on HIM to change and do the work now. Don't hold your breath.
