The time I broke up with my first boyfriend and then had sex with him in minecraft for the last time to show him empathy and he pretended to doxx me

Okay so I dated this shell of a man, lets call him Paul, for the sake of the Kiako lore
We dated from age 7-10, 3 years, and yes, he was my first boyfriend
I broke up with him when we were 10, because he started to take me for granted, treat me like a trophy, all that
I was one of the most popular girls at the time, and he was one of the most popular boys, so when I broke up with him in homework time, around 5 minutes away from home time
It was a pretty big deal, for one, we were, as I said, both popular, so everyone kept up with all our drama, and for second, me breaking up with him was seemingly out of the blue
He loved me still and didn't want to break up at all, so he obviously started ugly crying in front of the whole class and the teacher and when we lined up to go outside i kept apologising to him but he didn't even look at me
The next time we played minecraft, i suprised him with a 'sex dungeon' on our server and told him that we can have sex for one last time even though we already broke up, if he wanted to
After that, the same day, a few hours later while we were still on the server, building stuff together, he comes online with his alt, and starts saying all that creepy shit, about how he doxxed me, while saying that he doesn't know me
He stated my full name, school, home address, phone number and all that
KEEP IN MIND I WAS 10
i was totally freaked out and cried and begged him to leave me alone, and said he would leave me alone, only if i 'went back to Paul', who was actually him on that alt, I just didn't know it at the time
I promised I would and then did nothing, never went on that server ever again, and a few days later my friends told me it was actually Paul in attempt to get me to be with him again
