This sounds very encouraging. I know that things are very delicate right now, but it sounds like some real progress.
I'm particularly interested to hear how you consider deciding how to live in the same location again. My H and I are 5 hours apart right now, and that distance has really kind of put a hold on any real sense of progress. It allowed him to retreat to his corner and leave me in mine with almost no contact. It sounds like there are other parallels, as well, so your situation resonates with me. I wish you all the best.
