Choosing Fiancés Brother Over My Own as Best Man: AITA?

A 28-year-old woman refused to make her fiance’s sister the maid of honor, and somehow that drama still feels tame compared to this wedding-side-eye situation.

In this story, a 28-year-old man is planning his engagement wedding with his girlfriend of five years, and he tries to keep things simple: best friend as best man, then groomsmen choices after that. But when it comes to picking his best man, he chooses his soon-to-be brother-in-law instead of his own brother, even though his brother is older and they’ve been distant for a while.

Now his brother is calling it favoritism, going quiet on him, and the whole family vibe is officially cracked.

Original Post

I (28M) recently got engaged to my girlfriend (27F) of 5 years. When we started planning the wedding, we discussed who would be our bridal party.

My fiance had her sister as her maid of honor, so naturally, I chose my best friend as my best man. Now, when it came to deciding the groomsmen, I ended up choosing my fiance's brother over my own.

Quick context: My brother (30M) and I have been distant for a while due to personal differences and conflicting lifestyles. On the other hand, my soon-to-be brother-in-law (25M) and I have grown quite close over the years.

He's been supportive, fun to be around, and genuinely a good friend. When I told my brother about my decision, he got extremely upset and accused me of favoritism and betrayal.

He said that family should come first, and I'm disrespecting our bond by choosing someone outside the family. This caused a big rift between us, and he's been ignoring my calls ever since.

I understand his point, but I feel like my choice was based on who I have a closer relationship with and who I believe will support me better during such an important event in my life. So, Reddit, AITA for choosing my fiance's brother as my best man over my own brother?

I honestly don't know if I'm wrong here.

The Sibling Rivalry at Play

This story highlights a classic case of sibling rivalry, but with a twist. The OP's decision to choose his fiancée's brother over his own brother is a reflection of their strained relationship, which has evidently left deep scars. The fact that the OP's brother is older and presumably expected to take on the best man role adds another layer of complexity. It raises the question: how do you balance familial expectations with personal relationships?

When weddings often symbolize unity, this choice sends a message that, in this case, family ties are overshadowed by personal bonds. The OP’s fiancée's brother likely represents a more supportive figure, further igniting tension. Readers can relate to this conflict, as many have faced similar dilemmas in their own families, making it a hot topic for discussion.

That’s when the OP’s “we’re choosing who supports us best” logic collided with his brother’s “family comes first” rule.

NTA. It's about who will stand by your side, not a blood relation. Your brother needs to understand your reasons.
