Yoo hoo Mrs

Sorry you're having a bad night. Divorce is indeed shit ((((((((hug)))))))
I found it shit and I left him!
Darling, you have done marvellously. Really, you are wonderful - you have done spectacularly well. I remember the awful mess you were in when you first posted and you are simply not the same person. You have turned this around.
It is not surprising you were a mess. There is something really dark going on here imo. Can i ask you to do one thing? To stop trying to understand it - bcs it will literally drive you mad if you try. There is no rhyme or reason to this - you have to, you must, step away in your head and focus on your own life. Do everything you can to stop ruminating on the whys/how could theys.
I HAD to do this to save my sanity when I was being mashed to death by my ex. He was a frightening sort (as is this woman imo) and it was the road to mental and emotional ruin to try to work it out. So don't do it! 
I was watching some crappy but rivetting TV the other night and a man on the programme was telling the story of how he survived serious injury while mountain climbing alone. He said he focused on one thing at a time. He was in a truly dire situation but blocked the big picture out and just focused on one thing at a time - and he survived against impossible odds! My ears pricked up bcs it was such sound wisdom for when we're really up against.
So iiwy i'd focus on having a lovely evening, safe in your home
