AITA for saying I’m not going to a wedding I was invited to because the groom to be non- consensually put his fingers in my vagina during a game of touch football.

I (f23) went on a girl’s trip in Cabo and whilst exploring the nightlife we came across this group of guys. I got heavily intoxicated but still made it back to my hotel. I didn’t wake up until 4pm and missed brunch. When I made it back to the hotel my girlfriends and I played some touch football. One of the guys (23M), let’s call him M, was able to get me to the ground. (I was still hungover) I didn’t mind it but as I got up I felt like something was inside of me. I literally forgot that I didn’t wear any underwear because of my hangover. Long story short M stuck his fingers in my vagina. I went to the hospital and they confirmed it. <br><br>He never apologized and I never went to the police. This was a big mistake, on my part. I blocked him on everything socials. Fast forward 4-5 months I get an Instagram dm from his fiancé saying they’re getting married and she invited me. I said yes out of confusion. On the car ride home I realized she might have been with him when it happened. I asked her and she said yes. I told her I was the girl who got fingers in her vagina at the game and she nonchalantly said it’s in the past and to act like an adult. I said I’m not going and she said I’m petty. AITA??
