The present Mrs Hughes and I have separate bedrooms.
My lovely wife has ME, so her sleep patterns are all over the place, and she is a very light sleeper at night, so she often likes to read through the night, and she always sleeps with the bedside light on.
I snore because I am a borderline sleep aponea sufferer, so we disturb each other to intolerable levels.
Separate rooms means we both have our own space, and sleep properly and undisturbed.
When we go on holiday, I have a custom-made mouht device which prevents me snoring when we do share a bed, and I put up with her shuffling, rustling the paper, getting up and wandering about, and so on.
Of course, we do 'share' a bed - just not at night time!
