He told her that he wouldn't attend her wedding if their partner isn't welcome

Planning a wedding brings the best and worst in families. From guest lists to seating arrangements, the pressure to create a flawless "special day" often pushes boundaries to their limits. But how far is too far when leveraging family favors while cutting them out of the celebration? A viral dilemma shared by a person (u/personal-try-130) on September 1, 2026, has already received over 3,000 upvotes on Reddit in just 24 hours.
AITJ for not letting my sister use my apartment to get ready after she told me not to come to her wedding?

In the post, the author explained that months before their sister's big day, they agreed to do her a favor. Since their apartment was close to her wedding venue, they agreed to let her use their space as her bridal suite. However, the family dynamic changed when the bride officially uninvited the author's long-term girlfriend of 4 years. "My sister and my girlfriend have never really gotten along. Nothing huge happened between them, just years of little comments and arguments, and they basically avoid each other now," the author said. Their sister said they wanted to avoid any tension, so they uninvited her to their wedding. The author told their sister that they wouldn't attend a wedding where their partner isn't welcome.
The confrontation turned into a big argument, and eventually, their sister indirectly uninvited them from her wedding. "My sister said if that's how I feel, then I shouldn't come either," the author recalled. Despite uninviting her sibling and their girlfriend, the bride still fully expected to show up at his apartment at 7:00 a.m. on the morning of the wedding. In her mind, the guest list and free accommodation were completely two separate issues. She assumed that her uninvited sibling would hand her his keys as if nothing had happened. But when the author refused to let her use their space, she was shocked.

When the author questioned the situation, his parents jumped in, urging him to "let it go" because it's her "wedding day" and the agreement was made months prior. Confused by intense family pressure, the author took to the internet, summarizing the audacity of the situation: "I just find it weird that I'm not wanted but my apartment apparently is."
More often than not, people take undue advantage of their family members or someone close. According to a poll by the American Association of Retired Persons (AARP), one in five Americans knew someone who was financially exploited by someone they know. Similarly, a Pew Research Center survey found 77% of adults feeling obligated to help their parents during hard times, while 64% felt the same for a sibling. When we relate it to the Reddit post, the author also felt the pressure from their parents to help their sister even after she uninvited them to her wedding.


Meanwhile, reacting to the post, u/neither-ad9120 commented, "NTJ, going out of her way to exclude your partner and then you from the wedding, and then expecting to use your home for the same event is a wild thing to expect of somebody. Your parents should be setting her straight." Similarly, u/pixyfire said, "NTJ. There's no way I would let my sister use my apartment; if she uninvited me from her wedding, she can f*** right off."
u/Opening-Sir-2504 wrote, "Absolutely NTJ! She chose to say what she said. She chose to exclude your girlfriend. She is acting like a spoiled brat. She doesn’t get to use your apartment to prep for a wedding that she basically told you not to come to because she couldn’t get over herself for a day. F that, Batman."
