I’m getting married in a couple of months. My fiancée and I are planning a small, formal wedding at a nice venue we really love. It’s indoors, fairly upscale, and we’re trying to keep things elegant and simple.

My sister has an emotional support dog. He’s not a trained service animal, just a small dog she got a few years ago to help with her anxiety. Ever since then, she takes him everywhere. Restaurants, grocery stores, family holidays. She even tried to bring him to a movie theater once. It’s become kind of her thing.

When we sent out invites, we made sure to include a note saying no pets allowed. The venue technically allows service animals, but we figured this would cover all the bases. A few days later, my sister called and asked if she could bring her dog anyway. She said she needs him around large crowds or she gets overwhelmed.

I told her I understood, but we weren’t making exceptions. It’s a formal event, and having a dog there just didn’t fit. I suggested she bring a friend she feels safe with or take breaks if she gets anxious. She got quiet and said she’d probably stay home then, since she didn’t think she could handle it.

I told her that was her choice. I wasn’t trying to be harsh, but we’re not bending the rules just for one guest. Now she’s not speaking to me, and my mom’s saying I could’ve been more flexible. A couple of my friends agree. My fiancée isn’t thrilled about the drama but supports whatever I decide.

I feel like I’ve been reasonable. I’m not banning the dog to be mean. I just don’t want it at my wedding. It’s one day.

So, am I the asshole?
