It has got nothing to do with women's attitudess to their houses, Hyacinth Bucket or any other references
The simple fact is that some people by nature need mind space, time when they are alone and have not got people round them, others are the exact reverse. They are at a loss if there are no people around them and for some reason most marriages tend to contain one of each.
When we were younger and working, DH's job required a lot of travelling, mainly overseas and sometimes for a month at a time, so I got a lot of time on my own and never realised how important it was to me.
When I retired we bought a house with a huge workshop in the garden, which DH enthusiastically revamped and fitted out for all his various projects. But he is someone who likes to have people round him and quickly found he would rather do any project work indoors where I was there for company, rather than isolate himself and work in his workshop.
Thankfully within a year he went back to work - from home and until COVID and his heart attack, continued his business travel, which essentially he enjoyed. When COVID came. I found it very difficult to adjust to having someone around the house all the time, but I have carved out space for myself. I sleep less than him, so have time to myself in the early morning, There are times when he is out doing other things and I have the house to myself. He then has to accept there will be times when he is alone in the house when I am out.
I will not pretend it is easy, but we manage.
