Splitting rent evenly sounds simple… Until a third person starts using the same resources without paying a cent.

Guests come and go. At first, it was just a few visits a week. Then, he left some clothes. Later, a toothbrush appeared in the bathroom. Soon enough, he'll turn into a full-time resident without ever signing the lease. What happens when visits become almost permanent? Where's the line between a frequent guest and a resident? 

Living with roommates means learning to share space, routines, and expenses. It can be fun to share a home and enjoy company every day. Plus, splitting rent definitely helps your economy. Still, living with a friend is all fun and games until it's time to set boundaries. It might be uncomfortable to have these conversations, especially when other relationships are involved. But ignoring the issue isn't an option when a two-person apartment starts turning into an unofficial three-person household.

Utility bills rise, groceries disappear faster, the couch is always taken, the kitchen counters are filled with dishes that aren't yours, and the laundry piles up. Even small routines get disrupted, and you lose your moments of privacy. The constant presence of an outsider in your own home changes the entire dynamic. It's not just about money; it's about feeling like you can't truly relax at home anymore. This is what happened to a 25-year-old roommate who lost her privacy because her friend's boyfriend kept staying over every night. She spoke up and set her boundaries, but ended up feeling like 'the bad guy' when all she was asking for was respect. And she deserves it. Everyone deserves a home where they feel comfortable. 

Boundaries make a home livable. When a casual visitor becomes part of the house's routine, it's up to everyone involved to decide where the line should be drawn, and it should be respected.

  • I (25M) live with my roommate (27F) in a two bedroom apartment. We split rent and utilities evenly and have been living together for about a year with no major issues until recently.

  • About three months ago she started dating her boyfriend (28M). At first he would come over a couple times a week which I had no problem with.

  • But over time he has basically started staying here almost every night. At this point I would say he is here at least five or six nights a week, sometimes the entire week.

  • The issue is that he does not contribute anything. He showers here, cooks here, uses the laundry, and is around in the common areas most of the time.

  • I have also noticed our utility bills have gone up a bit, which makes sense with another person basically living here.

  • On top of that, I feel like I have lost some privacy in my own home since there is almost always someone else around.

  • I brought it up to my roommate and tried to be calm about it. I said I was not comfortable with someone essentially living here without contributing and asked if we could either limit how often he stays over or have him chip in for rent and utilities.

  • She got defensive and said I was being controlling and that it is her space too so she should be able to have her boyfriend over whenever she wants.
    via DrakeAnjos
  • Now things feel awkward between us and she has been kind of cold since the conversation.
    via DrakeAnjos
  • Her boyfriend is still here just as often and now I feel like the bad guy in my own apartment.

  • I am not trying to stop her from seeing him, I just do not think it is fair for me to pay the same while another person is basically living here for free.

  • So AITA for asking my roommate to either limit how often her boyfriend stays over or have him contribute financially?

  • NTA. x_III_x I used to be your roommate. I had my boyfriend over a lot. Then, with my roommate's permission, he moved in and started paying rent lol. It's a reasonable request.
    via DrakeAnjos
  • Radiant_Bank_77879 NTA. You are correct that he is essentially living rent free at your place, and he should be contributing for that reason. Even if he and your roommate share a bedroom, he still uses the common areas, too, and also the utilities. Also, having one roommate, you never agreed to sharing your living space with a third person. You are in the right, but that does not mean that she will ever see it correctly. It might be time to reevaluate whether or not you want to keep living with

  • EnigmaGuy NTA, but as others have said you need to ask yourself what you really want the end goal of the situation to be. Sounds like there are at least two factors here, and likely a third that is coming at any time: 1. Expenses / Financial Contribution 2. Privacy 3. United Front / Ganged up on. Living with other people is tough, doesn't really matter if its family, friends, or just cohabitating. Once a third party gets introduced that is on the other persons 'side' is when things generally sta

  • Covert-Wordsmith NTA. Go to your landlord and tell them about this lease violation.

  • ohwow28 I don't think it's about being an ah le, it's about being strategic about how you get what you want. If they agreed to paying more in rent/share of the bills would that solve your privacy issue? No. In many cases the only way to fix the situation is to remove yourself from it, i.e. move out.

  • ShmollMouse2025 NTA- there are boundaries to having guest, full weeks were someone is there is just unacceptable and they are not respecting that's it's your home also
    via DrakeAnjos
  • Firm-Psychology-2243 NTA, it shocks me how often this same scenario is asked. There should be a limit on how many days a week anyone can stay (I had 3 when I rented). Otherwise they're living there and they should pay. The 'l live here' argument goes both ways and your roommate needs to split time at his place too, even if he only has one pillow and an old towel.

  • Pure-Philosopher-175 I swear I see the same story multiple times a week. NTA. You signed up to live with one person, not two, and they are taking advantage of you by having you subsidise him living there. If your roommate isn't going to address this, then time to check your lease for conditions about guests and take it up with your landlord. Also, you are all adults - why not speak to him about it too? Ask him directly why he is staying so often and if he is willing to start contributing to rent

  • RegretPowerful3 NTA. Please look at your lease agreement. It may have stipulations about how often guests can stay over and she may be in violation.
