guys are a differnt breed

okay so uhm i need help im pretty sure this guy is obssed with me .... so me and this guy were talking on here like normal conversation about anime and manga , he asked me for my socials so i gave them to him and and then he started saying how hot and thick i was.(i mean hes not lying ) but still he told me he was over 18 and he clearly knew i was 15. Anyways i would ignore his uncomforatble remarks. so then he basicly asked me for nudes and then i blocked him but he had my socials so he text me from there and then i tried blocking him and he started yelling at me and sying rude things and in my mind im like yoo chill tf out obviously he is desprate bc a pretty girl talked to him and now he becoming fucking insane sneding me threats and not leaving me alone ..... like god dammit im dumb like i know better but yea anyways how is your day
