It feels like my partner is torturing me with sleep deprivation.

Throwaway account for reasons.
I (f28) have been with my partner (m32) for 6 years now. We bought out first home together last year. I have been dealing with diagnosed chronic illness and chronic pain for the past 3 years now the effect it's had on my mental health has been huge and I'm not the same person I used to be. I know I'm not as fun or spontaneous as I used to be and have acknowledged this to my partner many times. When I have little to no sleep my illness is worsened.
We've been sleeping in separate beds for the past couple of years now. My partner snores and thrashes in his sleep and I'm a light sleeper. Since we've moved in to our home together I'm getting barely any sleep. He's a night owl, so will play his video games loudly or music loudly. He will stomp as loud as he can. I don't sleep until he does because the noise he makes is so loud. He has small amounts of sleep himself but seems to be able to manage and function. So when he wakes up, I have to wake up. He knows I have insomniac tendencies, it can take me hours to fall asleep and can wake up numerous times throughout the night. Every morning when he wakes up he rages? Stomping as loud as he can, throwing things, slamming doors and drawers. One morning I woke up to this really loud banging noise. I snuck out of my bedroom and walked a different way to the kitchen. I crept up on him and observed him throwing cutlery full force into the sink, while staring down near where my bedroom is. This is what makes me think he does it on purpose. If I start to nap during the day from exhaustion he will stop me, by yelling, shaking me awake etc.
I've cried to him about this, I feel like death when I get no sleep, I get dizzy and can't focus on anything. My memory has gone to **** and my stress and anxiety levels are really high. I've expressed how this makes me feel and his response is "don't come crying to me about no sleep, I manage with little sleep". We have a joint bank account but I've been secretly stashing some of my own money aside to go and stay in hotel rooms to sleep. I feel guilty for this because I'm lying to him and telling him I'm going away on work trips. But I don't know what to do anymore. Any advice?
Tdlr; partner is not allowing me to sleep and I have to lie to him so I can stay in hotel rooms.
