hello. i'm an adult, 22m, but in my culture/country we all are unfortunately living in a joint family situation. currently, i live with my parents, my grandparents, and my aunts live in the same neighborhood with their families.
so my nine year old cousin is the daughter of my aunt and her husband. my aunt and i have always been close but have been struggling with friction because of her child's behavior generally being bratty. my aunt doesn't really do anything to discipline her child and she kind of spoils her. part of it is because my aunt feels guilty because my cousin is adopted. recently, my cousin has learned about her being adopted and its affected my little cousin mentally. my little cousin has begun to accuse my aunt of favoring other people over her.
anyways, my cousin was throwing a temper tantrum. the reason why was because i wanted to play on my switch and didn't let her, so it spiraled into her demanding her father and mother for a console, and sobbing about how she didn't have one. she started running all over the house sobbing and she saw my cat and ran out of her way to go and kick him.
i grabbed her and dragged her back when i realized what she had done. she started screaming and yelling and crying about how i grabbed her and how terrible i was. i explained what she did to my aunt, my aunt scolded her, but after that, my cousin kept trying to interact with my cat and running after him. i don't really know what to do because my aunt told me she scolded her, but i just don't trust my cousin anymore. i think hurting an animal in that way is really fucked up and insane, especially my cat.
my cousin is always acting this way and i'm kind of tired of it. my aunt freaks out whenever anyone tells her anything about her child's bad behavior, and she sort of engages in really odd behavior (overcompensating, maybe?) where she talks about how good her child is and how much she looks like me despite us looking nothing alike. i'm blonde and have green eyes, and she has brown hair and blue eyes.
what do i do from this point on? i was having a good relationship with my small cousin and aunt, but i just feel it's been sort of ruined because of this. whenever my cousin engages in bad behavior, i call it out, she throws a tantrum and accuses me or guilt trips her mother into it being because i 'hate' her cuz she's adopted.
