I’m 52 and my husband is 60. Separate bedrooms for the last 11 years due to OH snoring and fidgeting, and me being such a light sleeper, has saved our marriage.
I was having to have naps in the afternoon, driving to work while feeling so tired was dangerous, and my mental and physical health was suffering. I couldn’t go on like that.
The day my son moved out was the first day I’d had a good night’s sleep for years. OH didn’t really like it at first but begrudgingly accepted that he slept better, too, without being prodded in the ribs every night!
We tend to holiday in cottages and have separate bedrooms while there. The only time we share a room is when we’re camping, when for some reason OH rarely snores.
So, do what’s right for you. It’s nobody else’s business.
