Again it depends person from person, you don't have yourself to like it
My sister and her boyfriend won't share a bed cause they both move a lot and it's just annoying for them to sleep in the same bed because of that, and they've been together for 8 years
I believe the more you separate in intimate things (unless you are super on the same page) then you'll eventually drift apart. My sister and her boyfriend did the same thing sort of, but then they got 2 separate couches, etc. Turns out for a while they were just good friends living as roommates til they pulled the bandaid and broke up. It's hard to dislocate yourself from social and cultural norms even if we try. It's even harder to find someone on the same page. People change with the ebb and flow of what we desire, so I think it's probably more beneficial to do things together rather than try and make things better by separating for things that can end up mattering to either one. Like, there's a bunch of stories where people say, "I should have recognized the signs", and one of the bigger ones is you don't do things together, lack of intimacy, etc. So, yeah, more power to them, but I'll still have that lingering thought, and I wouldn't be surprised if any party involved doesn't have that from time to time.
Linking arbitrary things to signs of how much someone loves you can be problematic. If you and your partner are both asleep it doesn't actually matter where it's happening, Do you love your partner less when you stand further away from them?
It isn't really arbitrary. I'd assume most people don't go to bed, be silent, and fall asleep immediately (barring circumstances like they're super exhausted or whatever), I'd assume most couples talk or relax in bed together before they sleep. I'd liken it to you both having different meal times throughout the day just because of reasons even though you could spend it together.
