I've long argued for separate beds/rooms to be accepted, and seems like more and more it is.
We've never shared a bed other than at the beginning when she first would stay over, or the one time we tried a super king for a week before sending it back.
I used to want my own room, but have got used to sharing a room. We do however have completely separate beds. 2 doubles, pushed right up against each other, so it just looks like one massive bed.
We also go to bed and wake up as vastly different times, with a difference of about 3/4 hours each end.
Someone pointed out about how you get benefits from having good sleep and it honestly is such a bonus. The difference in moods for us is so clear after having good sleep.
I should add we do however nap together a lot, at least on weekends but also in the week day if we match being home early enough. And this we do snuggled together, so still have time to bond while asleep.
I strongly suggest people try sleeping in 2 beds and see how they get on and if their sleep improves.
