Snoring

My bf and I sleep in separate rooms. He snores really loudly, I get zero sleep if we share a room.

Different sleeping schedule

You've never slept wirh anyone have you?

because they're married? 🤔

it's what keeps them together lol.

Do you know how hot and uncomfortable it actually gets sleeping in the same bed with someone? To say nothing of the fact that some people are cover hogs.
