I (24W) have three toommates i am living with: Sarah (23 W), Rob (22 M) and Nina (26 W). We have moved in together in august 2025, but even before moving in there were some issues.
Nina has a partner she has been with for over a year now at this point, and before moving in she started saying how "worried" she is to live with the three of us, and how her boyfriend "does not want to visit" if our ouse will be crazy. At this point all we did was to joke about house decor and the living situation.
Fast forward to a month after moving in together and there already are plenty of issues: Nina became super passive-agressive to Rob and me because of chores, while Sarah had to go back to her home for a couple months because of paperwork ( we are all students). Then Nina became hostile towards me, and all i did was to point out her hypocricy when she complains about Rob. She forgets to clean her own dishes, never does the full list of weekly chores ( we have one room per person rule), and by that point was also complaining we do not cook her and her bf food when both me and Rob work as bartenders on friday nights.
After Sarah came back things exploded, with Nina saying she feels threatened by being at home because of me and Rob (wtf), and wants to move out latest april 2026.
Then christmas vacation happened and noone was home, but upon coming back home Nina and her bf started full on ignoring me and Rob and trying to suck up to Sarah by being waaay to nice with her. I called a house meeting ( with mediators per Ninas request) to resolve the tension because by this point i became quite depressed over being mistreated in my own home.
During the meeting i have pointed out multiple issues with me, the rest and Nina, including the consistent and constant prescense of her bf in our home. He eats here, sleeps here, takes shower here and takes over the living room ( sometimes without Nina at home). This strains our budgets because electricity during winter is expensive, as well as warm water. He never does any chores and complains when he has to clean after himself. Nina was sitting there as if i am attacking her, and towards the end of the meeting she promised to take care of her chores better and make sure her bf is not a strain on our household.
Fast forward to last 2 weeks of february and things escalated. I told her several times about the same issues from the meeting we held and she is either saying "its not me" or "sure!", but never acknowledges that she is in the wrong. Her bf seemingly hates me and Rob, and Sarah feels that Nina is trying to coerse her to "be on her side". I do not know what to do anymore, but i feel like i dont want Nina bringing her bf over anymore. They are loud, disrespectful to me and Rob, and are just not good to live with.
My question is as my title suggests, but any advice is greatly welcomed.
Let me get this straight, this chick is creating a hostile living environment for you and has a free loading bf? oh F that. You cannot live like this. Address the property manager what’s going on, that this person is not on the lease and find a way to legally evict them. If they want to play hardball, play their game better.
