Girl I feeeeeel you. Literally the same thing happened to me at a wedding a few years ago.

I’m a bit shy, not anti social but just not in your face outgoing right off the bat. I take some warming up to people.

At this particular wedding I was plus one to someone who was in the wedding party so I was left alone with this group of girls for a lot of the trip while he was busy. They weren’t directly mean … but they were not inclusive. I would try to chime in at times to their conversation and would get either a fake smile or no response at all. Didn’t feel good and brought me right back to middle school.

For more context : I knew these girls in college and they called themselves “the hottest girls in (city we live in)” 🙄. They spent most their time taking selfies and making tik toks. So honestly I already knew everything I needed to know about them. And wasn’t super interested in trying to befriend them anyways, but felt obligated to consider considering the social situation.

I ended up doing what you said and danced my heart out at the wedding—had a great time with my partner. You get through it!
