Hi 3, I love the 'I don't buy it' line. I may have to use that next time.
Your H is sensing that you are REALLY moving away this time. That's why the strange convo about a movie. He was trying to find something to talk to you about, anything so that he could see if you are 'still there'. Maybe just cut the convo short, saying I have to go to a meeting or I can't talk right now and then say goodbye.
Just keep doing what you are doing, and I foresee that he will keep trying to test your boundaries, so stay strong, but polite. Treat him like a roommate (someone told me this when I was struggling), that really seemed to help me.
I know it's hard, so hard. It succks, but you are doing quite well. Believe in YOU.
