Another great point. There has definitely been a pattern of not being able to accept ever being wrong or imperfect in any way. Right down to silly little things like blaming others if they can't find something, even though they are the only one who ever uses it. I used to have to buy and stash my own pairs of scissors, because my ex would repeatedly lose the communal ones - and blame me. Even once I was only using my own hidden pair, he would continuously lose the ones in the main drawer and continue to blame me. Every. Single. Time. Even though they were always found in his personal stuff or wherever HE had last used them lol. They just CANNOT be perceived as being at all fallible, even in the most minor and unimportant ways.
