I must have broken my SO's brain yesterday. For the first time he really asked me questions and tried to understand how my brain 'works', I have dysorthography (not sure if it exist in english - close to dyslexia but with grammar and orthography), and he's from the grammar police. So the fact that I cannot, for the life of me, put a concept that I could learn to heart (the words, not the meaning, I don't get it) and use it at the right place is just boggling for him.
My brain takes the written world as a big bag of confusion if I try to take part in it. I really wish he could 'get it' because it has caused me enough pain during my schooling* that I really wish someone would just accept it for what it is.
I can't blame him for not really understanding, it's like asking someone not on the spectrum to imagine what it's like to suffer from autism.
*That's what prompted the conversation, turns out, hearing (said or heavily implied) day in and day out, from 6 to 19y/old that you must be stupid, not making any effort, good for nothing, will leave traces.
