My H does a lot of the same things it sounds like. He doesn't want to do anything alone with me and in fact doesn't seem to want to give the appearance of being a "family" out in public either (yet he still lives here).
I am doing the same things as you - trying as much as possible to not be in the same room as him especially if he is there first, I wait for him to come to me, I try to be friendly and upbeat, etc. When he is in his pi$$y moods I just ignore, ignore, ignore.
Like the title of your thread, I am "cautiously optimistic" because I do see some glimmers . . .
And I do think your last sentence is the answer to all questions in regards to our MLCers!
