I put this in "Stump the Experts" because it's not actually based off my marriage/relationship. Still not in the mindset to tackle that recent drama.
this is the place to learn more about people, ourselves, and human nature.
the question isnt clear to me. are you wondering their motivations? what their personality style might be?
I'm not trying to link a DSM diagnosis to anyone. Something simpler than that, but more than "Yeah, people are just horrible to each other."
i hope this isnt the answer youre trying to avoid, but the fact is 30% of the population, at any given time, has a form of mental illness, whether it be a personality disorder, mood disorder, substance abuse disorder, etc.
far more than that have traits of PDs, or other sensitivities, or are just difficult people with difficult personalities... .bossiness, bad boundaries, poor filters, or are otherwise jerks.
if you get into bowens family systems theory, youll realize this stuff is everywhere, and can get more prominent in groups... .your church, your workplace, your school, your family. it is unavoidable. you need tools and skills to navigate.
so certainly... .
but will back down when you prove your worth or you confront them.
this is one approach, and with certain personality styles, will work. i had a really bossy overbearing guy in my church band who was always telling everyone else how to play their instrument, interrupting the director, starting drama behind the scenes. that style grates on mine, big time. the director handled him just fine. we stopped hanging out backstage, unfortunate, but no more drama. and when he tried to tell me what/when to play, i essentially told him no thanks, ill do it my way; ill bet he mouthed off about me when i left the room, but he never did it again and we get along great.
sometimes its as simple as that. different skills and tools work with different types. a pwBPD traits or style might have felt really rejected by me when they were only trying to help, so i might have used a different approach.
does this help? are you looking for something more specific?
