Do you and your SO go to bed and/or get up at similar times?
When I was married we did.
Normally we are on the same time. I tend to do the extrems if we are not. If not I go to bed at 7 when the kids go to bed or I'll stay up until midnight. I'm naturally a night owl but our kits get up at 5:30. The nights I go to bed early I had insomnia the night before.
My last GF worked a different shift. Why we broke up.
My SO doesn't exist.
Hubs works second shift and I'm up all day with the munchkin. I'm up at 7 and down about 1 am. He's up at 2pm and down about 3 am. I stay up so I can see him for about 5 mins a night.
My wife turns in at about 10:30pm; I stay awake until 3 or 4am. We get up together at 7am. I nap some during the day to shift the weight on my bedsores.
Me and myself get up at the same time.
We've been on very different schedules the last couple years. I miss being on the same schedule.
It is nice to have the bed pre-warmed... :)
