AITAH for not wanting my brother’s girlfriend at the house anymore
So recently a few months back me (F18) and my brother (M 19) moved into a house to get away from our mom and the toxicity. We agreed bills will come first and that we’d only worry about getting stuff for our rooms and kitchen and bathrooms and worry about the living room later on.
A few months after we moved my brother began talking to a girl at my work who I will call Serena. It was fine at first, I thought she was cool and stuff. But then everything changed. A few weeks after they got together, she’d caught my brother cheating and decided to break up with him.
On this same day, he was texting her trying to get her back he crashed our only car. This lead to us having to take Ubers everyday and I only found this out because he was using my phone because his was broken.
Well they worked things out but it seems like they’re still cheating on each-other, he found out she’s been texting multiple guys and girls and she found he’s still texting girls. It go so bad to the point where she called one of the girls over our house and the girl and her friends all fought him while she stood by.
He cried that night because he hit a woman and asked for my opinion on the matter. I told him that he wasn’t ready for a relationship and he should clearly focus on paying the bills and getting us a new car instead of whatever mess he has going on.
He clearly didn’t listen.
They got back together which was fine. I don’t care that they’re hurting each-other by cheating but it started becoming annoying when they’d fight verbally in the living room and the fact that Every-time I come home, she’s there. Not just one or two days but it’s like every-time she gets off or work at night she stays over. We hardly have any food here and he never alerts me when she’s over.
They were just fighting outside and it lead to me arguing with them over this where Serena said that it wasn’t any of my business weather they argued, I’m just wondering if I’m butting in too much or being a weird sister. It’s just embarrassing and annoying seeing two adults act like that.
