My brother keeps having loud sex to get back at me.
I (19F) live with my step brother (24M) at our parents house. Our parents both work away, so sometimes it’s just us home.Recently he’s been bringing a girl over and they’ve been having loud sex in the living room while I’m awake and home. The living room is separated from the bedrooms by a door that they repeatedly leave open, so it’s impossible not to hear what’s going on. On top of that, he’s doesn’t help clean the house (even if the bins full he won’t take it out, he’ll just pile shit on top of it) and as of recent left piles of pubic hair in our bathroom (specifically the shower) and when I’m talking piles, I mean PILES.
The ridiculous part is I actually tried to be reasonable. A few days earlier he mentioned bringing a girl over and I literally told him I didn’t care as long as they kept things respectful, clean, and left me out of it. Clearly that didn’t happen. For context, we’ve never been close. He’s my step sibling and there’s been years of family issues, lying, drama, entitlement, and conflict that with him and his biological mother have been the root of (this has also taken a massive toll on my mother as over the years there have been long stretches of time where our lives were horrible, not to mention that her life prior to meeting my step father was already unimaginably hard). My immediate family has mostly tried to keep the peace around. We usually stay out of each others way and honestly just try to keep the house running because I’m the only one who cleans when my parents are away.
I’m at the point where I genuinely don’t know whether to confront him again, involve my parents more directly, or just disengage completely. I’m also the type of person that once I’m angry I’m angry, I’ve genuinely started to think about messing with his food, clothes and car because I don’t think having a normal conversation would stick. I don’t want constant drama in the house since I’ve dealt with a similar situation with other family before but I also feel disrespected in my own home and feel like I can’t even walk around in my own house.
How the fuck do I deal with this?
