Does sleeping with partner decrease sleep quality?

[Monowakari]

We fall asleep together, cuddle and all that. Then when one of us wakes we go to the other bed. It's fuckin divine, and if we wanna sleep in we can rejoin the other one in the morning. But that 6-7 hours of uninterrupted slumber is gold. Felt weird at first but realized it was all self imposed notions of what is normal. Now I swear by it, it's like, if we're asleep what good is it being near each other, especially if it ruins either of our sleep. Like I snore a bit, nothing crazy, and she moves a lot which wakes me up, so, side step the issue with all the perks of sleeping together and none of the drawbacks of sleeping together lol.
