You are not alone. The couple who bought my house moved into separate bedrooms saying they feel it’s more “civilized”. I slept with my ex husband for 28 years even though his snoring was always a problem.
When a new partner moved in with me, he didn’t want to sleep in the same room because of different sleep patterns and the fact he likes his 2 cats with him. I’m not a fan of cats.
In a way it feels like we are more like room mates than a romantic partnership, but I think that’s mostly in light of the fact I slept with my ex husband for so long that it felt like the norm.
