My (23f) bf (24m) is driving me crazy with how rude he is at night because he?s a light sleeper and I?m not

My bf and I have been together over a year and living together about 6 months. He?s an EXTREMELY light sleeper. We never used to have problems but I?m now on medicine that causes me to have more insomnia so it?s harder for me to fall asleep. Lately, we?ve gotten into fights because he?s being absolutely unrealistic about any noise in general. I can?t clear my throat quietly, sneeze or even yawn without him grumbling, groaning, or yelling at me at how ?loud? I?m being. When I say yawn, I don?t mean some exaggerated TV yawn, but literally the sound of me silently taking in and expelling air from my mouth 3-4x over the course of 2 hours sets him off. Sneezing is very rare and it?s also quiet but if I have to make any noise, I do it as silently as possible, but it?s not enough for him. When I was extremely sick with the cold, he made ME sleep on the couch because I was having a tough time sleeping without being able to actually blow my nose to breathe. But, when he caught it a week later, I gladly let him sleep in the bed and helped take care of him when he woke up in the night because he wasn?t feeling well.
I?ve argued with him multiple times that it?s unfair for him to expect absolute silence and be mad over the AIR he hears from a YAWN but he just shuts me down and tells me to be quiet because I?ve disturbed him from being ?right on the edge of sleep.? I understand that when you?re half asleep you?re particularly grumpy, we?ve all been there, but it winds me all the way up that I already constantly have to cater to the way he needs tons of space (meaning I have to sleep pencil straight all night or on the side not facing him if I want to move my legs at all) and then this sound thing. I?ve had previous bf?s who were heavy sleepers that snored, made lots of noise and honestly that bothered me less than constantly having to be alert to his needs.
He says that ear plugs don?t work and he only likes to hear the fan so white noise is out of the question. I don?t want to go downstairs because then I?ll just stay up and I don?t want to keep taking melatonin every night but I?m this close to not renewing our lease together next year if things don?t change. It also makes me feel like if we got married and had kids he?d just expect me to be up all the time dealing with the baby so he can sleep or complaining about his sleep or if one of us was to have a chronic sickness that we?d have to sleep in different bedrooms because of how selfish he is. What should I do?
TL;DR: bf is being selfish and unrealistic about any noise, no matter how quiet, that disrupts him from sleeping
Edit: for now, sleeping in separate bedrooms would not be an option since we live with 2 other roommates until we graduate from college in May so the only other spot is the couch which would be inconvenient for everyone involved. Also, I?m not the kind of person that wants to sleep separate from their partner if I can help it.
Edit 2: WOW. This is my first post to have ever blown up. Thank you everybody for all your insightful responses! Truthfully, a lot of you are correct in the fact that his selfishness and gaslighting extends to many other parts of the relationship. There have been many times where we?ve almost broken up but he always wants us to work out so it doesn?t happen. Personally, I had life threatening blood clots in my lungs over the summer (hence the medicine I have to take to live which makes me an insomniac) that he was there for every step of the way. So it?s hard to end the relationship after going through something like that with someone you love and worrying that the next person wouldn?t get all the feelings that come with it. I?m going to talk to him again and see what compromises HE can bring to the table. If not, I think it?s time for a break.
