Its traditional. You get used to it.
My wife and I shared the bed for most of our marriage. There were issues, but we both slept pretty well most of the time.
She snores.
I'm a sleepwalker.
She flip-flops in her sleep.
I can't have my fingers/hands touching any part of my body.
She has a "wave machine".
I sleep with earplugs in.
We slept apart for the last year of our marriage, and we both still slept just as well.
I always thought it would be best to live next-door to my wife, not just in separate rooms. Better yet, how about a block away?
