So I share an apartment with my roommate, and when we first moved in, we agreed it would just be the two of us—no live-in partners or anything like that. A few months in, her boyfriend started staying over more and more, to the point where he was basically living with us. I brought it up a couple times, and eventually she said he’d start paying a portion of the rent and bills.

Now, technically he’s a tenant too, but it still feels like he just inserted himself into our space. He’s always in the kitchen, takes super long showers, and it just feels crowded and different from what I signed up for. I still pay half the rent, and I barely get alone time in the apartment anymore.

She thinks I’m being unfair since he pays now, but I feel like I lost the home dynamic I agreed to. AITA for still being annoyed?
