I guess I’m in the minority that I have a harder time sleeping without my spouse than with. I realized about six months in that I’d rapidly developed some sort of dependence where I would fall asleep quickly if I spooned her. She had surgery in January and spent several weeks in the guest room so she could avoid the stairs, so we’ve tried being apart. It is nice if you have the space/budget for a king bed, though, to spread out from each other some.
