My W does the ignoring thing sometimes too and then if I don't react or walk away or call her on it, she changes, just like it seems your H did.
I think sometimes we just don't see what we're doing and after we walk away or call them on it, they realize it. Probably something totally unrelated to you that put him in a mood and you were just lucky enough to be there when he decided to vent.
Water off a ducks back.....
Congrats on the Town Clerk deal.
