Im putting this down to living in some sort of psychosis detachment from reality, it is the best I can offer.
that might be a little strong. a double standard, or hypocrisy, is not the same thing as psychosis or detachment from reality.
you know those studies you hear all the time, you see in your facebook feed, you hear in the news? there was one that i heard at a very young age, and it really stuck with me: people bond more easily over things they dislike.
ostensibly, you and i would better bond over talking about movies we hate, and why, than movies we love, and why.
universally true? scientifically true? i dont know. like anything, it probably comes with a lot of caveats. try too hard to bond with someone over negative things, and theyre going to see you as a negative person, much like compliments can build a relationship, but overdo it, and the person is going to question your motives.
but generally speaking, people watching, cracking jokes, talking about "omg i hate that too!" can bond any couple.
this really has very little to do with low self esteem, or high sensitivity, the things that a person is personally wounded by, except the most obvious dangers...if i non stop find fault in others, a romantic partner is bound to eventually wonder if i hold them to the same standards.
Surely if you are a person who is so super hypersensitive to perceived sleights or criticism, what part of such disorder is there in the textbook to say that you can do the same to others? Surely you would feel so wrong about it happening to you that you wouldnt?
that would be nice, but i dont think most of the people ive known operate that way.
