I work days and he works nights, so I’ve usually just gone to bed when he’s driving home. He generally comes up for a goodnight kiss and possible conversation or shenanigans if I’m still awake, though.
Other: Another work schedules don’t overlap; we each sleep when the other is at work.
I need to change my vote–I said yes and it’s perfectly fine with me, but then saw the dog/cat thing; I wasn’t thinking of pets when I voted.
Also, it’s perfectly fine with me most of the time, but of course sometimes I wish there was another warm body in bed with me. A human one, I mean. Male.
Since I moved in 7 months ago, I get into bed alone but he arrives in a fairly timely fashion. I drift to sleep to the sounds of him grooming himself.
My husband and I have separate bedrooms. Been about 3 years now I think and we both love it. We usually sleep in the same bed 3 nights a week or so. We generally go to sleep around the same time, although I’m usually in my bed a little earlier and out of bed earlier as well. We kiss each other goodnight every night and good morning, etc. and make late night visits to one another, we cuddle for a bit before sleeping, sometimes we’ll read in bed together, all that jazz.
We are both just much more comfortable sleeping alone. I move around a lot, he’s very still. I’m always cold, he’s always hot, etc.
It’s nice not having to worry about keeping each other up or waking each other up or anything like that. And it’s nice when we do sleep in the same bed too.
norinew, we are in almost the same boat, only my husband is usually (but not always) home every weekend. We’re going to be in this situation until we sell our house, and as we can’t lower our asking price until our contract with the RE agent runs out in Feb., we’re going to be stuck in this situation until then, at least.
After years of sleeping alone with few qualms, I now hate it with a passion. Our neighborhood has had a number of break-ins in the past two months and I feel like a sitting duck. Our cat comes and goes during the night, usually in silence but sometimes I’ll sense that she’s bumped the bedroom door open and I just have to turn on the lamp to be sure it’s only her.
This! In my case it usually means the partner gets an extra six hours of WoSW…
I love sleeping alone. But I’d let the cats in the bedroom if they weren’t so prone to vomiting.
Haven’t slept with my bf in about 2 months cause I’ve been on a project assignment. I miss sleepytime snuggles. 
When I’m home though, he always comes and lays in bed with me until I fall asleep, and then gets back up to do whatever night owls do.
…and over here it’s Dragon Age. 
(I get my playing done in the morning instead)
I go to bed alone, because evidently that is the way everyone else wants it. 
I often wonder if I’d be able to adapt to living with anyone. I have been on my own since I was 16 and now I’m 45 and three times I’ve had roommates, and that is about a year in total for all three.
I’ve never dated anyone long time or had a relationship so I never had the excuse to “stay over.”
I reckon it’d be hard to get used to sleeping with someone after a lifetime of not doing it
No cites, but this is IMHO, so I won’t bother searching one out. 
But I’ve been told that the only group with a higher divorce rate than those that get married under the age of 25 are those who have their first marriage after age 40. And I bet you can guess why that might be true: you get used to doing things your way, it gets harder to compromise, it’s tough on a relationship.
I can’t seem to sleep without my lovie next to me. sigh I love him.
Other, specify:
No, I have a spouse/partner/SO that’s with me MOST nights. Sometimes she is elsewhere, sometimes I am.
This is my situation as well. I don’t even like TV that much, and am more of a early to bed early to rise type.
The spouse likes to stay up/doze with ESPN, then eventually come to bed a couple hours after me.
And yeah, we’ve got pets in there with us, too.
