I (25F) have an older brother (27M) who recently left his shared living situation. My mom, sister, and even grandparents are pressuring me to let him move into my apartment because I have an extra bedroom but I said no, and now everyone thinks I’m being selfish and unreasonable.

Some context: my brother has a long history of violent, erratic, and abusive behavior. He’s struggled with drug use, spends his last dollars to feed his addiction, and has frequent angry outbursts. When he lived with our mom, he put his hands on her, screamed at her, destroyed property, and even physically harmed me and other siblings. When he tried living with our grandparents, he threatened them too, so they kicked him out.

When we were teenagers, he also acted very inappropriately toward me. He tried to convince me to sleep with him and attempted to touch me. He never followed through, but he manipulated me and bought me things so I wouldn’t tell our parents. My mom knows about this. Her response? That “he was just a teenager” and that I should “forgive and forget.” My sister also thinks I should just “set boundaries” if he starts acting up.

Now he’s staying in a hotel, and everyone is suddenly looking at me to give him a place to stay despite literally everyone else refusing to live with him. I told them I’d rather downsize to a one-bedroom apartment than share a space with him. I’ve never felt safe around him, and I don’t trust him not to harm me or destroy my home.

But now my mom, sister, and even grandparents are calling me heartless for not helping him out. I feel like I’m the only one who remembers how bad things were or they just want to pass the responsibility on to me.

So… AITAH for not letting my brother move in with me?
