I'm 18F and live with my parents and my brother (20M). He graduated high school a couple years ago and hasn't gone to college and doesn't work. He doesn't even contribute to bills around the house.

His rooms a mess, dirty stuff everywhere. My parents do his laundry. He doesn't do the dishes. He leaves the toilet seat up all the time. He spends most of his time gaming in his room.

Last night, I went downstairs into the living room a bit after midnight because I couldn't sleep. He had his pants pulled down on the couch in the dark under a blanket and was masturbating to his phone. I said "What the f??" and he mumbled and ran off to his room.

I told my parents he needs to stop acting like a loser and that he should get a job and move out. My mother was disappointed with him but said we shouldn't push for him to leave. My dad told me not to tell him to move out and to not make him feel unwelcome. It seemed they were more upset at me than him. I've just had enough of him when I'm working a little bit and have to do the chores and he doesn't contribute and has been getting in my space while I'm stressed from school.

AITA?
