New here, this is my story...

HelpMe,
Been following along.

Again, our goal is NOT to stay married (well, that is her goal), but only to build communication and rebuild trust to be good parents through and after divorce

Hmmmm, Then why did she choose a Marriage Counselor (unless he's also a Family Counselor)?

(but when she agreed to this, she added that "if more happens, great").

Well, this could certainly be good. Not slamming the door shut. Baby step. Towards (perhaps). I'd also build on her choice of words, here. When with the MC you might want to mention something like, "I'm not here to see what happens. I am definitely here to make things happen." (in addition to admitting you've been an a$$hole, of course)

For now, I can just head to bed, knowing that tomorrow is another day and pray that I get the strength to get through it and the do the same thing tomorrow night.

Good. And don't pray to just get it: pray to be able to summon it up. You've got strength already.

I'd like something...even if it is just a thread of hope.

Maybe you are that thread of hope...for your family.

Keep going.
