My sister (29F) got married last weekend, and I (26F) honestly still don’t know if I overreacted. For context, my boyfriend (28M) and I have been together for about 2 years. My family likes him overall but my sister has always made weird comments about him being too charming and saying she wouldn’t trust a guy who’s nice to everyone.
At the reception, everyone had been drinking and during one of the games my sister suddenly announced she had proof that men can’t be trusted. She then told everyone she had one of her bridesmaids dm my boyfriend from a fake Instagram account a few weeks before the wedding to see if he’d flirt back. Apparently he responded politely at first but once the messages turned flirty he stopped replying entirely. To me that sounds like he passed the test.
But my sister kept insisting the fact that he responded at all was a red flag. Then she read parts of the conversation out loud into the microphone in front of everyone. People were laughing awkwardly and my bf looked completely blindsided. I got angry and asked her why she thought humiliating my boyfriend at her wedding was appropriate. She said it was just a joke and that if I was secure in my relationship I wouldn’t be upset.
my bf wanted to leave immediately so I left with him without saying goodbye to anyone. then about an hour later my mom started texting me saying I caused drama at the wedding and made my sister cry on her big day.
Now multiple family members are saying I should apologize because it was only a prank and I embarrassed my sister by storming out.
But I honestly feel like what she did was mean and weirdly invasive.
AITA?
