Been with my wife for 14 years. She’s a light sleeper, I’m the opposite and bit of a snorer. After moving in together, I would drop off to sleep straight away whilst she takes a while so would get cranky at me snoring and kick or push me. Me, having a lovely sleep, would then get annoyed at being woken by light ‘physical abuse’ (😜) and get cranky at her.
We sleep in our own rooms now and works fine. Definitely a stigma about, I’ve never mentioned us sleeping separately to friends etc but there’s no reason why there should be really. Do what works best for both of you innit.
Apparently, sleeping in the same bed is a relatively modern thing which society has forgotten about. That’s what she told me anyway!
