AITA for Accidentally Revealing Old Accusations to My Bully’s Girlfriend

I (17f) have a bully (16/17m). When I say bully, I don’t mean it lightly. Not too long ago (when when we were 14) calling my dad a p\*\*\* alongside a number of other really racist comments when working on a project he proposed about racial discriminatio. Basically, he’s really racist (not uncommon for where I live about Indians) and is a obnoxious asshole about it. As to not provoke too many rules with his behaviour as a person, he has shoved me and stuff that’s not super bad but is super unheard of since I go to a really prestigious high school.

This led to recently when I went to a summer internship. In it I was talking to a few girls from another school and we were gossiping about people in our schools (I knew the people they mentioned) and I brought up this guy who we will call A.

A had a huge scandal when we were 14 where almost every girl in his class had reported him for being a creep. He had flash drives of photos of girls (amongst other stuff that would break the sub’s rules if I mentioned). This is just an important and not physical thing (there is more). The flash drives is the only thing I can actually confirm did happen since when a acquaintance of mine had filmed videos of it and shown me since he was also part of the group reporting him. I never kept anything from the incident since it wasn’t my buisness but when gossiping with people from other schools and talking about things in this nature, I do sometimes bring it up (though I never usually name him), but more often I talk about to talk about his ***direct actions to me.***

In this case I did, what I did not know is that A had a girlfriend, a girlfriend who happened to be *in front of me*. She prodded and I tried to explain. I don’t know what happened with them, but from what I heard she didn’t break up with him. Regardless, it was an incident and I chose not to involve myself with the girl because of other reasons.

Now, when we came back to school in August I passed by A when getting my bag from the class. He cussed me out for mentioning fake rumours to people. Here’s where I’m unsure if I’m fully wrong (I’m not unaware of the fact that I’m being kind of a petty asshole here):
I didn’t say something that wasn’t real, he did actually have this incident happen and got taken to the office for it but never had a suspension or an official report of it (our school seldom suspends people due to the nature of how rich and powerful the families coming here are). And most importantly, I didn’t do something he didn’t do (he was trying to spread rumours about my dad like I mentioned earlier but I didn’t pursue it further). The other thing is that I also didn’t know that his girlfriend was the person I was talking to, otherwise I wouldn’t have said anything.

So reddit, AITA?

Edit: I just wanted to add a little info about my school and A which I answered in one comment; My school doesn’t suspend people unless they are physically violent and i haven’t heard about them ever expelling someone which is most likely due to that power-money thing (a lot of stories that prove this that I won’t divulge). A’s family is rich (at least I think so), so he’s not one of the kids of UN agency members or embassy kids. However, A is nutoriously disliked by most of our grade. This situation definetely created that but A is pretty rude to most people, and is very discriminatory to many groups and very obvious about it. I’m not liked in our year (I’m a very loud person in nature) but he is very disliked. As far as I know, he only has one friend in our grade.

Also in regards to the actual incident that happened: I did walk away and I lied that I didn’t know. He tried to bring it up in front of a teacher who actually managed the first incident I talked about (when he said stuff about my dad). That teacher likes A for his work but is especially fond of me since when I was in his class, I was an especially agreeable person and I have always been a very enthusiastic student. In his incident, when he ran his mouth, I found out via a friend (who overheard him but was also somewhat friends at the time) telling me and there are multiple emails that detail his actions towards me from a number of sources unlike with mine.

Also! This guy is still mad at me which is why I brought this up again is because of another recent incident that made me want to get an unbiased answer as to whether I was really wrong for this, especially when I didn’t even intentionally get into this situation.

Last note for this edit: I saw some people saying I’m AI, trust me, I WISH I WAS. This whole situation is, unfortunately, part of my life. If my writing gives of AI, it’s because I’m a writer and I’ve learnt to write like this after years of writing. That’s why.
