This is something that was difficult for my SO to understand when we first moved into our TINY one-bedroom apt together. at the time our work schedules were pretty identical (both worked nights with the same two days off) after a while I had to switch my schedule up to just give myself one day a week where I could be alone.
it’s nothing against her at all, i absolutely love her and i love her company, it’s just that for my whole life there was really nobody but me and there’s no way to change how i’m wired..sometimes i just need solitude and that does make me feel bad but i don’t know any better.
I think it’ll be easier after i finish school and we can get a bigger place where I can have my own space, but for now I’ll just keep looking forward to my 9 or so hours alone every Wednesday evening.
