My sister Lena’s friend regularly screamed at her, made fun of people, was ableist, etc.
She is on-and-off nice and mean. Right now, she’s nice. Before, she hated Lena. Now, she likes Lena. In a few months, she’ll hate Lena again.
Lena’s friend believes nothing is ever her fault and refuses to get help. She is very secretive and guarded, and acts very paranoid. Along with her defensive behavior, this makes me think she’s sadly being abused if she isn’t just a jerk.
She has quite the ego, but I’m not sure if it can be justified. Lena wants to be her friend and help her even with her behavior.
(She apparently has NPD)
Other people are not your problem, if she has any negative effect on you and those close to you, really recommend cutting her loose and later if you want to give her another opportunity, you can try again after everyone’s grown up more
