All relationships are different and things that work for some couples don't for others. Sleeping in separate beds is one of those things. Growing up, I never realized that my grandparents having separate bedrooms was out of the norm, but as an adult, I realize that they clearly just weren't compatible bedmates. Maybe one of them snored or hogged the bed. Whatever the reason, it worked for them; they were married for over 50 years!
I personally think one of the best parts about a relationship is sleeping together. You have an instant bed warmer, someone to cuddle with throughout the night, and someone to wake up next to in the mornings. That's just me, so what about you? Would you ever consider sleeping in separate beds from your significant other?
