It isn't anger, it is frustration. You play a lot of games with yourself that get in your way.
I don't believe you when you say you are fine with H falling asleep and going to another room to finish a movie. I believe you resent it along with his history of sleep apnea deeply. Thus, knowing it hurts H when you finish the movie elsewhere, it looks a lot like punishing H because of your resentment.
Glad H is using his CPAP. Has H had his sleeping disorder evaluated recently? It sounds like his treatment is insufficient if he is still showing significant signs of sleep deprivation.
