I am no DB expert by any long shot. (Far from it.) I really don't know how close you are to your goals, your hopes, your needs in this. From what I have gathered from other folks' accounts, you seem to be at a point in this crisis where it really could go either way. Your H is still in the fog, but he is no longer ruling out the possibility of a life with you. I can't tell you how much better that is than not.
You seem to always have your head on right, and now is no different. You are showing the perfect degree of cautious optimism, while still preparing for any outcome. It is still precarious (even scary) for you, but you appear to know how to balance the extremes. I am still in awe of how you are handling this.
You deserve to succeed in this, Lwb. Very much so.
