I actually sleep in a seperate room to my Wife i;m 42 and been together 23 years (not seperated.)
My son has cerebral palsy and he sleeps in the bed with my wife, he's 7 but the size of a 3 year old so he sleeps in the double bed with my wife, too old for a cot and too small for his own bed really.
so OT advised this arrangement. He has a special sleeping system that he has to use that fits the bed and it basically cocoons him, bit like memory foam and big thick blocks so he can't flail around.
Anyway, means i have been relegated to the spare bedroom for the past few years, least i'm away from the snoring... makes it hard to get any loving though.
Especially as well have 2 other kids in the house.
On the plus side, I can play games and come to bed late without disturbing her.
I actually like sleeping alone. it's cooler in the summer and so peaceful at times. just that one major drawback.
