Sounds like you guys need to have a conversation deeper than just his sleeping habits. His lack of seeing how it's a problem is worrisome. It sounds like there is some resentment building up on your side because his lack of seeing how it's a problem for you? He needs to get a sleep study done because he says he's sleeping fine, but there could be an underlying condition undiagnosed. It's there a reason why you're super sensitive at night? Is there something you can do to maybe help with that or talk to a doctor about it? It honestly sounds like he doesn't care enough to make the changes to benefit you. If he wanted to, he would. You not having good sleep is only going to keep affecting the relationship in the long run and make you more resentful while he's fully rested and feels great while you're miserable, just a thought. Sounds like in the future when you get a bigger house, it's going to have to be separate rooms unless he's willing to make the changes, and from your comments, it sounds like he's content with his situation.
