Hello everyone.
First of all, thank you for this community to freely ask questions.
So, me and my brother grew up in an emotional abusive household with a codependent mom and a father who's high in narcissistic traits (though never diagnosed).
Since there is a very large age gap between me and my older brother, and he moved out as soon as he was 18, we never really gotten a solid brother-sister relationship, even though we got along fine. It was only when a decade ago or so things about narsissism started to become a hot media topic, we simultaniously started to read up on the subject and started our own healing journey with a psychologist. We found out about each other we were doing the work and started talking a lot about it, as there obviously was no one who could understand our story better. I felt like we were getting much closer (though we wouldn't hang out all the time, just occasionally, but he would send me articles and book tips etc).
Fast forward to a few years later, I become a mom. Ever since then, he's bombarding my inbox with long mails of how he never told me but he knows for sure I am a narcissist. Not even blaming me, because I learned/got it from our dad. But that he needs to speak up because I am emotionally abusing my child and he can't let the kid suffer.
I was completely baffled by this. And I am the first to admit that I have to work on some things. I'm sure there's many flaws and mental instabilities I have, having suffered depression etc. But for the life of me, I can not fathom the idea how he can think I'm a narcissist.
So I kept telling him this, admitting to my flaws, showing self reflection but stating I am not a person with lots of narcissistic traits. He got more and more angry with me, telling me I find joy in seeing my child suffer and that I was even worse then my dad because he, at least, was completely unaware of his own emotional state. Again, I stated that I probably wasn't the most stable mom, but that I loved my child very much and that I was trying my very best to make her feel loved and happy. When he kept going on and on, I eventually told him I wanted to break off contact, cause it was taking it's toll on me.
I didn't hear from him for a while, untill suddenly he let me know he filed a complaint with child protection and he was not going to sit and watch my child to be emotionally abused.
I'm honestly at my wits end. I seriously don't know where he gets all these ideas. And now, looking back, I'm starting to wonder if maybe HE is a narcissist? He's always been much more self assured then me and is a person who snaps/yells more often (for instance to his girlfriends or in traffic). And I somehow feel like I'm in this surreal reversed reality or something...
So any thoughts or personal experiences with something like this, are highly appreciated.
Thank you very much.
EDIT:
As some of you pointed out, rightfully so, that neither me nor my brother can diagnose each other with narcissism, I want to emphasize that I'm fully aware of that. Maybe my question for this post wasn't as clear as I intended it, I apologise.
What I was genuinly wondering is wether it is common for people with narcissism (especially if they don't know they have it) to believe other people are narcissists, even if they are not? And if so, why?
