The spectacular misunderstanding on here is classic.
We are at the end of a year of lockdown.
So, prior to lockdown, many of us did things out of the house, like go to the gym,or go out with friends, or travel for work, or just ANYTHING.
For those of us at home, (I wfh) instead of having a week full of ebb and flow of people, everyone is there all the time and it is bloody exhausting.
All the OP wants in some alone time.
How is that hard to understand?
In her case her dh wfh has massively impinged on her daily life.
It requires readjustment.
It really is not about entitlement and 'get a job' and 'I'm sure he would liek time alone too'
It isn't either/or. She needs time in the house alone. I'm sure he does to. Or not, some people don't. If we weren't in the middle of Covid, some of that happens naturally.
One person goes out for a drink
The other pope to shops
One meets a friend
The other goes and does Sat am Park Run
etc etc
But non of those things are happening are they? so we are 24/7 with same people and no decompression space or time.
Worse if you have kids I think, especially teens/young adults as there is no evening.
