I don't find myself surprised at your W's actions or job loss in the slightest. It is really echoing what is going on with my XW. They are so lost it isn't funny. I am wondering if she might be drinking? My XW has lost her job and is now on social assistance, back to drinking lots and to look at her you would think she was in her 50's. It's really sad how far they can fall and I really think now that they do need us to simply be there when they need us. I know that my XW deeply regrets what has happened over the last couple of years, I still get nonsense phone calls, I think because she needs to hear my voice or something ( I might actually see her in person once a montyh these days)
You seem like you are in a good place mentally and sound like your strength is returning. Time will allow you to gain strength and perspective, funny how it works but it does every time.
