AITA for wanting out an apartment I signed with a childhood friend?
For context, I(19F) and my fiancé(21M) share an apartment with one of my childhood friends(20F). Me and my partner were in a bad situation before we decided we needed to get the hell out. My friend was looking to get out of her mom’s house, for reasons I’ll disclose later on, when I started the application process with her she wasn’t prioritizing getting things done. I had to constantly remind her to finish her application that I had started for her until she did. When we got approved for the apartment they asked for the basic’s. (i.e. paystubs, security deposit, our basic information essentially) She had to constantly be reminded and I would get constant calls from the apartment office on her behalf. Me and my partner had started regretting starting this process with her and we wanted to back out but by then we had already been approved. We spoke to several people who know us both and they all asked me "Why would you move in with her?". To be fair it seemed like a good idea in the moment because me and my fiancé were desperate to get out. Moving day arrived and she was supposed to help us move our heavy stuff but instead she didn’t so me and my fiancé used my moms car and later in the day I rented a uhaul to move our heavier stuff. The first week was okay ish, we’re still trying to get used to everything except she has 2 cats and wanted to bring in her dog, which me and my fiancé said no since we also have our own cat and don’t want her getting hurt. Small things start piling up, her cat is constantly howling(she left him in the closet), her cat keeps knocking the trash over after, she lets dirty dishes pile up, the fridge became extremely cluttered and the litterbox needed to be cleaned BAD. Me and my boyfriend silently cleaned up after her but we became fed up after having to constantly clean up after her and just being behind her all the time. I started telling her about these things but she told me that she can do what she wants because her names on she lease. She keeps repeating that phrase "my names on the lease" but she doesn’t do anything relating to the apartment besides paying her bit on rent & bills. My fiancé and I really can’t take it anymore, theres a constant mess outside in the living room, it smells, her and her boyfriend are hiding garbage on the balcony, and she’ll just walk around it like its not an issue. I feel trapped because the lease isn’t over until January 2027 and breaking the lease will cost us a significant amount. Is there anything I can do? And am I the asshole in this situation?
TLDR; My roommates is extremely filthy, Im constantly cleaning up behind her and I’m exhausted.
