AITAH For considering dropping my wedding because of my Fiance's obsession with making the wedding perfect?

So, I (30M) am getting married to my fiancée “Lily” (29F) in September. We've been together for 4 years and I love her deeply—but lately, this wedding planning has made me question everything.

Lily has been planning this wedding since before we got engaged. I'm not exaggerating. She had a full binder, color-coded tabs, mood boards, spreadsheets—the whole nine yards. At first, I thought it was cute. I was like, “Great, at least one of us knows what they’re doing.” But it quickly spiraled.

Every single decision has turned into a battle. I suggested we skip the cake tasting and just go with the bakery her sister used (which was great), She cried and said I was "rushing her dream." I wanted to include my 8-year-old niece as a flower girl, Lily said she “didn’t fit the aesthetic.” My niece is eight. She’s adorable. The aesthetic is a child throwing petals. What is this, the Met Gala?

The final straw was last weekend. We were going over the guest list and I noticed my friend Marcus wasn’t on it. I asked why, and Lily said he “doesn’t match the vibe.” I asked what that meant and she said, “He wears those loud shirts and tells weird jokes. He’ll ruin the photos.” I told her that Marcus has been my best friend since college and he was in the hospital last year. If he wants to wear a pineapple shirt and crack dumb puns, he’s still coming.

She got all quiet and said, “Well maybe your priorities aren’t aligned with what this wedding is supposed to represent.”

That’s when I snapped. I said, “If your dream wedding is about curated photo ops and not about actually marrying the person you love, maybe you should just marry your damn Pinterest board instead.”

She burst into tears, called me an a**hole, and left to stay at her sister’s. Her family is now texting me about how I "humiliated her" and am “too emotionally immature for marriage.”

Was I out of line? I get that weddings are a big deal, but aren’t we supposed to be the priority—not matching napkins and symmetrical table layouts?
