AITA for Not Giving My Sister a Plus-One to My Wedding?

Weddings are supposed to be joyful, but guest list decisions can create unexpected drama. One bride refused to give her sister a plus-one to her wedding, leading to a family fallout. Was she justified, or did she take it too far?

My Sister Expected a Plus-One – But I Said No

I’m getting married in a few months, and like most couples, my fiancé and I had to make tough decisions about our guest list. We’re keeping things intimate, which means only close friends and family are invited—no automatic plus-ones unless the person is engaged or in a long-term relationship.

My sister, Emily, has been casually dating someone for a few months, and she assumed she could bring him. When I told her no, she got upset and called me selfish for not including her boyfriend. She argued that she wouldn’t know many people at the wedding and didn’t want to come alone.

I explained that if we made exceptions for her, we’d have to do it for others, and that would add too many guests. She didn’t take it well and is now telling our family that I’m excluding her. My parents think I should just let her bring him to keep the peace, but I don’t think I should have to change my wedding plans for someone she may not even be with in a few months. Am I the asshole?

The Community Reacts: Was I Justified?

Many people agreed that not giving a family member a plus-one to a wedding was a reasonable choice.

“A wedding isn’t a casual party—guest lists have to be controlled.”

“If you made an exception for her, others would expect one too.”

“It’s your wedding, not hers. She doesn’t get to demand a plus-one.”

However, some thought I could have been more accommodating.

“She’s your sister. Giving her a plus-one wouldn’t be the end of the world.”

“If she’s uncomfortable going alone, maybe you could reconsider.”

“Weddings should be about family. Is this really worth the fight?”

The Verdict: Guest List Boundaries or Unnecessary Drama?

While some believed I should have bent the rules for my sister, most agreed that not giving a family member a plus-one to a wedding was my right.

At the end of the day, weddings require tough decisions. Would you have made the same choice? Let us know in the comments!
