there’s some days where she’ll want to talk to me, follow my accounts, say things to me, and then call me an annoying b*tch.
she’s nice in public, i’m assuming so others don’t think she’s mean, but what i mainly don’t understand is why she talks to me since she hates me so much and did nothing but harm me.
Abusive people are generally selfish and manipulative. As such, they know that abuse has to be 1:1, with the appearance of normalcy to everyone else. Being rude in public would cede their abusive power over any individual.
EXCEPT
When abusive people gain a critical mass of followers in public, the behaviour reserved for 1:1 interactions goes public, and they start behaving in public like they always do in private.
A good example of this is Donald Trump.
That sounds like one of my parents. They are a narcissist.
They’re doing it to save face and appear nice. They know they rules of society and push them as far as they can to gain advantage. If they know that being mean to you gets the same results as being nice, they will be mean.
