The conversation about packing your things and moving that you recounted with your H reminds me SO much of the round and round conversations I would have with my ex. Then the later texting to you with the total mood swing later is exactly what I have been living for the last couple of years.
You sound like you did a good job on not reacting to any of his bait. That is what will free you from the constant emotional termoil.
Best of luck, it's a long road ahead. I like the sound of your post and not letting him suck you into his drama.
