AITA for getting my roommates boyfriend evicted?

A 23-year-old woman finally snapped after putting up with her close friend’s boyfriend living rent-free in their shared townhouse for over a year. He took over common spaces, broke house rules by having sex there, and even made a new roommate so uncomfortable she moved out—just for the couple to celebrate it.

With six girls splitting the rent and each having their own room, the setup worked fine until the boyfriend moved in without asking anyone. Fed up, she went straight to the landlord and reported him as an unauthorized tenant, getting him evicted. Now some roommates call her the asshole for going behind their backs, while others cheer her on.

‘AITA for getting my roommates boyfriend evicted?’

The house has been home to multiple roommates for years, with plenty of space and no major issues:

The boyfriend started staying full-time without discussion or contribution:

Attempts to address it didn’t go well:

In anger, she contacted the landlord:

And a positive update:

Living with roommates requires clear communication and mutual respect, especially around guests and shared spaces. When one person unilaterally moves in a partner without agreement, it disrupts the balance and can feel like an invasion—particularly if they’re not contributing financially or respecting rules.

Housing expert and author Vicki Robin notes in discussions on shared living: “Unauthorized occupants not only strain resources but can violate lease terms, putting everyone at risk” (inspired by common advice from sites like Nolo on tenant rights). Here, the boyfriend’s presence exceeded guest limits, overcrowded the home, and created a hostile environment.

Going to the landlord without a group discussion first can escalate things, but after 1.5 years of issues—and the couple celebrating scaring off a paying roommate—it became a necessary step to reclaim the space. Better timing would have been earlier, with a united roommate front.

In the end, the house is back to comfortable, and Sue’s choice to leave shows where priorities lie. Protecting your living environment isn’t wrong when others ignore boundaries.

Here’s the feedback from the Reddit community:

The vast majority backed her fully, calling her not the asshole for finally ending the freeloading nightmare:

A rare dissenting voice suggested everyone sucked for poor communication:

One cheeky take:

This saga of an uninvited live-in boyfriend highlights how one person’s entitlement can turn a harmonious shared home into a nightmare. She endured way too long but ultimately restored peace by enforcing the rules everyone else ignored.

The online world overwhelmingly supported her move, with many shocked it dragged on for 18 months. Ever dealt with a roommate’s partner overstaying their welcome? Did talking fix it, or did you have to go nuclear like reporting to the landlord? Tell us your war stories below.
