hey BM, I've been lurking and reading your story and I'm thinking that yeah, maybe you should push him a little to either sh*t or get off the pot.
That may not be very DBish, but you need to take care of you and your son. Once your H goes or doesn't then at least you'll have some calm (hopefully) in your home to think. And if he goes he'll have time to think (and maybe miss you).
My 2 cents...
