Mighty, I'm so sorry you're feeling sad today. I wish we DBers had a way to meet in person but for now I'll have to settle for giving you a virtual hug. (((((MIGHTY)))))
I could have written much of what you posted..... This whole experience is just surreal.
I don't know your history in great detail, but reading how you grew up together, know each other so well, etc..... I have a hard time believing such a sudden life change with decisions made during crisis will be a lasting positive for him...but who cares.
The good news is that it can, and will be for YOU, no matter what. Because you are here, you are aware, and you are one of the strongest people I know.
One day he'll think, "Wait.....my poorly thought-out, selfish and hasty decision didn't solve EVERY SINGLE THING in my life and make ALL my problems magically disappear without having to look at my own issues? Now what?"
Time will tell.... Meanwhile, I think you are one remarkable woman. I don't know how you've done it all.
