Definitely separate bedrooms. As someone upthread said it was only paupers in the past who shared beds because they couldn't afford more, the aristocracy always had separate wings. And who decided that it would be comfortable sharing a space between 4&6 ft with another person?
Tomorrow is our 36th wedding anniversary and we have slept in separate rooms for more than half of that. He likes to burrow down, heavyweight duvet, windows and blinds closed for a full 8 hours. I sleep best with the windows and blinds open, lightweight covers, and I wake frequently in the night and get up and potter about.
If we had to share a room I think we would be divorced by now.
Good question. Who DID decide sharing a 4 ft wide, 6 ft long bed with another person to try and 'sleep' for 8 hours, was a good idea?! Even a king bed (superking whatever!) is still sharing! And you will still suffer from his snoring, and getting hot, and him quilt hogging, and coughing etc.....
I think people have superking beds - so they can sleep as far apart as possible from their husband, and wear earplugs (and try and pretend he is not there,) whilst still being in the same bed. Rather than actually admit that they need separate beds - as they see it as some kind of failure in their marriage. It's really not. It's an absolute fucking treat! Just get separate beds FGS. Separate rooms even (if you have a spare room!)
Like you, I could not have slept with my husband long-term.
I know a few old couples (over 70,) who have slept in the same bed for 45-60 years, even though she - yes SHE - does nothing but moan about his groaning and grunting and farting and snoring. Yet, even though they have one or two spare bedrooms, she refuses to sleep in another room, because of the 'shame' of man and wife not sleeping in the same bed.
Same with several very religious couples I know; despite HIS heavy snoring and HER lack of sleep, they would let hell freeze over before they don't share a marital bed. I mean, what on earth will people say?! 
Batshit. 
Ya know what? I don't give a shiny fucking shit! 
Got my own room, had it 15 years, and I fucking wubz it!
FUCK what other people say. I am happy and so is my husband. And quite a few women I know are rather jealous.
