Ok, thanks for the clarification.
For me, my well being and happiness comes before money. That, however, is an individual choice.
I was 58 when I tossed exabf out, yes, I had to make some financial adjustments, but I have prevailed, no regrets on my part.
Do whatever is best for you, if you decide to stay then you must accept him for who he is, as, he will not change, you can only change you.
I would suggest meetings, they will help you learn how to detach.
Take care!
