Vent?? EX infodump

I'm not sure if this is a safe place to vent but I kinda wanna infodump about my ex cuz I lowkey feel bad   

small tw?? dunno if it's needed     

Alright so, I met this person named Mocha about one or two years ago and we became really good friends, he was actually a really cool person back then. We realized we live close by so we met up often, hung out a lot etc. A few months later we started dating which went wonderfully, until Mocha started having some mental problems and also became a proshipper. At first I didn't care, cuz I don't wanna base my attraction off of that but it became really weird. He made genuinely disgusting comments about literal children and started sending me p3d0/inc3st related ships even tho he knew I was uncomfortable. I blocked him on all platforms, but he didn't leave me alone. He texted me on multiple accs in a creepy way but after a while he gave up. About a month of all of this, I was forced to join a server on discord. I was kinda blackmailed by the owner, cuz he somewhat knew my address and quite literally threatened me. Anyways, a little bit later Mocha joined the server and started spreading rumours about me, for example like me being 30 (As I said we met up irl HE KNOWS I'M 14) and a lot more. He made nearly all my friends turn up against be with random bullshit he made up. A little bit later, he actually fcking k1ll3d himself and some ppl have been blaming it on me when I didn't do anything  ?? I do kinda feel bad but I don't at the same time, pls someone tell me if I'm in the wrong or not
