Portia gave you good advice, BF.
Your H shows signs of depression and MLC. Does he really think he has 15 years left?
If he wants a D, let him file. Don't do it yourself. I would not do it without a L. My first choice would be collaborative, and mediation second.
I know how awful you feel. Let the feelings be. At the same time, don't linger in that low place too long. Remember YOU have a life to live too! Sometimes I only wanted to disappear. I didn't want to live. I look back, and see how consumed I was with negative emotion. It's not worth it.
Sending you a big hug ((((((((((((((((())))))))))))))
