Thanks, brokenhearted. Unfortunately, right now my H is not ready to work on the M, or at least not ready to tell me he is. There are hopeful signs, and you're right that he doesn't know how to fix things and wishes he did, but mostly he wants space & time right now, which I am giving him.
I just thought there might be a guide here about any "best practice" ways to respond to an A, in case I have to deal with it. I want to hit the ground running, instead of driving my H back to the long-d EA, which I did before.
