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.
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.
