Wedding disagreements can get complicated very quickly, especially when family relationships, long-term partners, and unspoken expectations all collide. In this case, OP thought he was simply doing his sister a favor when he agreed to let her and her bridesmaids use his apartment to get ready on the morning of her wedding. He lived conveniently close to the venue, and allowing them to use his place would save the bridal party the additional cost of a bridal suite. At the time, there seemed to be no reason to reconsider the arrangement.
But the situation changed dramatically when OP’s sister decided that his girlfriend of nearly four years was not welcome at the wedding because of their longstanding tension. OP understood that his sister could ultimately choose her own guest list, but he did not feel comfortable attending a family wedding where his partner had been deliberately excluded. The argument escalated until his sister told him that if he felt that way, he should not attend either. OP accepted that decision—but then questioned why his apartment was still expected to play a central role in a wedding he was no longer invited to attend.
My Sister Wanted To Get Ready For Her Wedding At My Apartment Because I Live Conveniently Close To The Venue And Her Bridal Suite Would Cost Extra

Everything Seemed Fine Until My Sister And My Girlfriend’s Years Of Small Arguments And Tension Suddenly Became A Much Bigger Problem

After Nearly Four Years Together, I Thought My Girlfriend Being At A Family Wedding Was Pretty Much A Given Until My Sister Told Me She Was Not Welcome

Apparently My Sister Thought Being Uninvited From The Wedding And Letting Her Use My Home Were Two Completely Separate Issues

But From My Perspective, It Feels Strange To Be Told That I Am Not Welcome At The Wedding While My Apartment Is Apparently Still Welcome To The Entire Bridal Party

Time to see how Reddit weighs in on this drama.


The real issue here is not simply whether OP should let his sister borrow his apartment. It is about whether a favor that was offered under one set of circumstances should automatically remain available after those circumstances have changed completely. OP originally agreed because he wanted to help his sister have a convenient and less expensive place to prepare for her wedding. But after being told that his girlfriend was not welcome and then being explicitly told that he should not attend either, OP understandably began questioning the expectations being placed on him.
His sister apparently viewed the wedding invitation and the apartment arrangement as completely separate matters, while OP sees them as connected because his willingness to provide the space was part of supporting her wedding. His parents believe he should keep his original promise and avoid adding stress so close to the big day, and there is certainly an argument that changing plans at the last minute could create unnecessary problems. On the other hand, OP is not demanding that his sister invite his girlfriend or change her wedding plans; he is simply withdrawing access to his own home after their relationship reached a point where he was no longer welcome at the wedding. Ultimately, the question is whether refusing a favor after being excluded makes OP petty, or whether his sister cannot reasonably expect him to facilitate a celebration from which she has deliberately removed him.
