I met a guy in my middle school a few years ago, I didn't talk to him much but we were in the same group of friends, he was always too strange for my liking, He's one of those guys who has his phone full of inappropriate games and makes you play them without telling you what they are about.

A few months ago I entered high school and he didn't have any friends,I felt a little bad so when he talked to me or asked me for drawings I tried to be nice to him. He got my number from the school group and sent me a lot of messages, screenshots of +18 mangas or song lyrics in English (I'm from Mexico, so that was kinda weird),Also, I didn't feel very comfortable around him anymore because of some comments he had made in the past or because of the content he consume.

He spammed me with many messages every day And uploaded videos of me without my consent to his tiktok, I ended up getting fed up so I told my brother if he could talk to him so he would stop, my brother's classmates already knew about the situation and weren't very happy about it, so they threatened him via text message,It worked for a month but then he came back more annoying.

Not long ago he dropped out of school with a threatening message in the school group and he keeps sending me insults through WhatsApp statuses,He keeps calling me a whore and things like that, He has posted coded messages where he says that I'm going to hell and he also keeps saying that "no one will feel sorry for me on the internet"

He starts commenting like he's a talk show host and responds to anything I post or do, literally once he called me a slut because I posted that I was excited about the Minecraft movie.

Also, he uploads conversations with his Discord friends where they insult me and I'm worried that he'll ruin my reputation or upload something more serious if I'm not watching

Honestly, I don't think I ever did anything wrong to him. The only thing I ever did was insult him because he made a rude comment about my scars (I've been struggling with mental health for some time so I got angrier than I should have)

My parents don't know about this situation and I don't want them to know. I feel like I can solve the problem myself, but it's getting tiresome.I tried to talk to his mom before but she just told me that that wasn't her son,I know I should block him but I feel like I'll lose this "battle"if I do, as if he got away with tormenting me.

My friends are already fed up with me telling them about this and they say I'm just as obsessed with him but I don't feel that's true
