'AITA for having my younger brother move in with me without my dad and his girlfriend's approval?'

A 21-year-old woman turned to the popular 'Am I The A**hole' (AITA) forum to ask if she was wrong for swooping in and taking her younger brother away from their dad and his girlfriend—without their approval.

In a post titled, "AITA for taking my brother to live with me without the approval of my dad and his GF?" the original poster (OP) shared how her family situation became a mess.

Her parents divorced right after her younger brother, 19, was born and her mom took them to another country. Things took a turn years later when their mother sent OP and her brother back to live with their father while they attended school in their home country.

OP notices several red flags after moving out of father's home for college

At first, life seemed fine. Their dad started dating again, and both siblings supported his efforts to find love. Enter Sarah—his new girlfriend. She moved in, and while Sarah was initially nice to OP, things deteriorated once the latter moved out for college.

The trouble began during a casual check-in call with her dad and brother. OP described how one day, she heard yelling and crashing noises in the background. When she asked what was going on, Sarah barged into the room, grabbed her brother’s phone, and ended the call.

"This freaked me out, and I made plans to go back as soon as I could," OP recalled. "When I arrived, I called my father that I came to surprise him and spend the weekend with them (as an excuse). He immediately responded with 'I think you should go back.' I was shocked and asked him the reason, then he said they ‘were fine’ and hung up," she said.

When OP arrived at the house, Sarah answered the door and refused to let her in, claiming everything was fine. OP didn’t back down and managed to get inside, only to find her dad reading in the living room, acting like nothing was wrong. Things escalated when OP insisted on seeing her brother, eventually making her way to his room.

What she saw shocked her.

Her brother’s room was practically empty—just a bed and a small table. According to Sarah, she had “thrown [his belongings] out to purify his soul so he wouldn’t become corrupted like [his sister].”

"I was appalled by this and looked at my father to see if she was serious, but turns out he also agreed," OP continued, adding, "At that moment, my dad tried to take him away from me and that’s when I left that house with him. Now he lives with me and my roommate."

Now, her brother is much happier, applying to colleges nearby and building a new life away from their dad and Sarah. "I’m telling my mother next Friday what happened since she’s coming to visit me," she wrote. But the drama didn’t end there. OP’s dad has been bombarding her with texts and calls, accusing her of “breaking the family” and “hurting her brother.”

OP couldn’t help but wonder: Did she do the right thing? "Did I overreact? Should I talk to my dad and his gf?" OP asked.

The internet weighs in on OP's intervention

The Reddit AITA community rallied around OP, reassuring her she absolutely made the right call.

"NTA. Your brother is a legal adult. It sounds like they were holding him with some sort of force or coercion. Talk to your mom and see if it's something your brother should talk to the police about. Keep the messages from your father and don't block him in case your brother needs them as evidence," one responded.

Another offered: “What Sarah did to your brother is absolutely unacceptable, and your dad enabling that behavior is even worse. You stepped in to protect your brother when you saw he was in a toxic environment. Your father’s manipulation of the situation is troubling, and his guilt-tripping you into thinking you’ve broken the family is not fair...You did the right thing.”

"Your brother's a legal adult - he can live wherever he wants with no need for anyone's "approval". You saved him from their abuse. NTA," someone else added.

"That is cult-ish behavior, lol. Why is she talking about purifying your soul?" read a comment.

"NTA—You did what any good sibling would do. If your brother is happier and safer with you, then you made the right call. It's about his well-being, not your dad's new relationship dynamics. Keep supporting your bro!" another insisted.
