@hunkydorythefish YANBU. This would drive me bonkers.
Me and DH have been together every day - (just me and him as DD has left home,) - since last March, (on furlough) apart from a 3 and a half month month spell between late July and early November. We have different hobbies and do stuff separately... We also have a few of the same hobbies and do some stuff together.
He goes to bed around 9.30pm and I go at around midnight. He gets up at 7-7.30am and I get up at around 9.30-10am. So I have time to myself at night... And HE has it in the morning.
I go for walks alone too, 3 or 4 times a week, (for one to two hours,) and a couple of times a week, I go with DH. We watch some TV programmes together, but sometimes I watch one of 'my' programmes on netflix or TV catch-up, on my laptop, whilst he watches one of 'his' programmes on the TV.
We definitely don't do everything together.
We also have SEPARATE BEDROOMS! Which (IMO) is the key to a happy marriage. We have had separate bedrooms for about 14-15 years, and I would NEVER go back.. It's utter bliss.
I never really liked sharing a bed and a bedroom with him, as I love my own space. I had my own bedroom in my parents house growing up, and also when I lived on my own for several years before me and DH got our own place together.
After 10-11 years or so of living together, DH started to snore at night... After another 3 or 4 years, it got so bad that I told him flat out that I was making the spare bedroom mine, and was no longer sleeping with him. (We still had/have sex, but I went/go back to my bedroom after...)
He was more than happy with this, as he got as fucked off with being jabbed in the ribs, shoved and poked, and woken up because of his snoring, as I did of spending every night struggling to sleep, and suffering from sleep deprivation.
I honestly can't fathom how anyone can share a bed with their partner long-term, for 30, 40, 50 years plus. My older relatives (grandparents/ aunts and uncles/ great aunts and uncles, older neighbours etc etc, etc,) shared a bed with their spouse til the day one of them died. But the women in each couple complained profusely for YEARS about the other one's snoring, grunting, coughing, and rolling about in the bed and poking them.
But no WAY would they have separate bedrooms. 'What kind of married couple has separate bedrooms?' a great aunt of mine said once? 'Oh the SHAME!' 
I thought 'a sensible married couple, who want to make sure they get the sleep they NEED! That's what kind of married couple sleeps in separate bedrooms!'
This attitude (from some) that a married couple must share a bed forevermore, no matter how uncomfortable or unpleasant it is, is extremely bizarre and VERY outdated.
