@PrizedPickledPopcorn and @heatdeath describe a lot of my experience with my DH.
I don’t exist to him except if something I do irritates him, or when he needs to rant to someone. And he has no awareness of time whatsoever - but also no idea that he has no awareness of time. He thinks it’s normal not to know what day it is or what month it is.
He’s also had difficulty staying in work. He works freelance and is always quitting contracts because the work is boring / everyone else is doing things wrong / the system doesn’t make sense to him. He’s also had at least one contract ended due to his low productivity, because he zones out half the day on his hobbies (he works from home so I see how he spends his time).
His memory is so poor that it is like living with someone with early stage dementia (which I have done recently so I know what I’m talking about). He loses things all the time, forgets appointments, loses his phone.
You can have whole conversations with him that he has no recollection of ten minutes later.
He can’t make decisions at all. His shoes have holes in them and he can’t replace them because the model of shoe has been discontinued and he doesn’t know how he would decide on a different kind of shoe. So he puts plastic bags in between his sock and shoe to keep the water out.
He is, however, not at all frightened or made anxious by any of this, as he is clear in his conviction that he is right and the rest of the world is unreasonable, and everyone who remembers things he does not is trying to gaslight him.
And he seems to genuinely believe that intending to do something is as good as actually doing it. And he’s a good person with good intentions, and people just try to malign him all the time and he doesn’t understand why.
He has absolutely no awareness of how poor his executive function and memory are, and how different his experience is to other people’s.
He showers once a week if that, but insists he doesn’t smell (he does) and I’m being horrible and controlling if I ask him gently please to have a bath.
It is crazy-making and extremely anxiety producing over time, and really erodes your sense of self.
