I actually bought a bigger [wider] bed,because I have to share the damned thing with a Dachshund and a Corgi,plus two cats! HOWEVER....they all sort themselves out at the BOTTOM of the bed. I don't mind at all-but with the 6' wide bed,there's plenty of room and I don't mind at all....and yes,the bedding IS regularly changed. Every month,whether it needs it or not!
I think part of it-- at least the way I view it or have experienced it... I have not minded sleeping alone for quite a long time. I think it's pretty nice actually. I get to stretch out on the bed and take as much room as I want... if I wanna watch tv in bed I don't have to worry that someone else may want to sleep and I'd be bothering them.... but back to my point, I think sometimes with people who haven't slept alone for a very, very long time and then all the sudden they have to sleep alone for at least a night and often more- it can feel really, really strange when you're not used to it at all. I remember I was like that once myself. It can just feel really weird and lonely when all the sudden you're used to someone being there and all the sudden...they're not. However hubby works 3rd shift now (3 or 4, 12 hour "nights" a week) so I have been used to for years having at least half of the nights just me. And I like both. It's nice when he's there. I like waking up and he's there. But I also LOVE falling asleep alone...stretching out on the bed with a bunch of pillows...whatever. I often find it's the most restful too. Unless I'm feeling worried or anxious about something, then no.... but that is not often, thankfully.
