Sister hitting sister
I’m the oldest (F21) of 4 and my middle sister (F15, Julie) is constantly harassing my youngest sister (F8, Madeleine). As a kid, my brother (Josh- now M19, but when this was going on he was 5-12ish), was always hitting and beating Julie because, in his eyes, she took away all our parents’ love. When that was happening my parents would reprimand my brother but I don’t think they were very validating to Julie, who is now really narcissistic (I don’t say that lightly) and takes out her anger on Madeleine.
For example, today we took a road trip for 5 hours and Madeleine wouldn’t plug in Julie’s phone because the wire would touch her shoulder. They were arguing and yelling in the car about it throughout the trip. And now that we’re at the Airbnb, Madeleine told us that Julie hit her 5 times on the thigh super hard and threatened to lock her in the shower if she told us what happened. This has happened before on worse degrees. Despite Madeleine crying and clearly in pain, Julie just insists that she’s faking it until she realizes that nobody believes her. Then, she goes on about how Madeleine deserved it because of what she did in the car. Then my parents will decide to turn off her wifi and ultimately, she’ll be like “Wow so you love her so much you love her more than me because when josh was hitting me you didn’t punish Josh” etc. Which btw isn’t true because they did punish josh. Whenever me or one of her older friends has told her about how she shouldn’t continue the cycle of abuse on Madeleine, she cognitively understands but still continues to do it.
I feel at my wits end about this honestly and I would really appreciate some help about what to do or say to her that might be helpful. My parents and I would put her in therapy but she 1) doesn’t think there’s anything wrong with her and 2) gets super defensive if someone does insinuate that she needs mental help. Does anyone have any advice🙏thank you for reading this far if you have
