boyfriend is angry because of a leaked balloon pop challenge video where it looks like another guy is fucking me. Is he right to be angry?

At new years eve I did something stupid. My boyfriend already went home and I stayed with only a couple male friends of ours. I was really drunk and didn't think about the fact that a balloon pop challenge could kinda get outa hand, especially with this one guy. I don't remember that much, but one of the guys filmed it and sent it around, also to my boyfriend. my dress was all the way above my ass so this guy was practically doing this against my thong. He was really disrespectful and was really taking advantage and acting way too dirty. He slapped my ass till his handprint was in my ass the next day, he pulled my hair, grabbed my boobs and stuff. He was calling me a slut while doing it and said to the camera that my boyfriend now had something to jack off to the entire year. Of course, that is really bad, but I was clearly to drunk and didn't mean anything bad. I totally get that he's angry, but why only at me and not at his friends? Why not that one guy who did it and the guy who filmed? Is he that scared? What are your thoughts?

If you don't know what a balloon pop challenge is, it's this kind of thing (and no, that's not the video of me):

I think this is a troll account.
