Separate beds, is it weird?

My husband and I sleep in separate rooms and people always have a negative comment about it. I will state it started out because I get up early to go to work and he’s a light sleeper and once he’s woken up, he can’t go back to sleep so he’s cranky and tired the rest of the day. So he started to sleep in the guest bedroom days I had to work then eventually it turned into every night. Initially I minded it, but now I am happy because I can move around in bed without worrying about waking him up.

I guess my question is, do other marry couples sleep separately? How do you handle when people make comments?
