My brother’s girlfriend is round our house constantly. He brings her round for weeks at a time. She practically lives here, they’re both pushing 30 and don’t pay any rent, they make so much mess and don’t clean up after theirselves. I’ll be watching rude/inappropriate stuff out loud because I think I’m home alone, only to then hear her exit the room next to me after it’s been dead quiet for hours. I never get the place to myself, I can’t be myself in my home, I’m fucking sick of it.

What the fuck do I do?
