So I have have done bad things in the past that I thought was over till this guy kiked me and started talking to me. Some how he got pictures of me that i sent before. and he started using them against me. Saying if I dont give him a blowjob, have sex with him and make out with him he will send it to everyone on my Facebook. He is very smart because he doesnt even know me and he looked me up on Facebook. anyways, he has been kiking, texting =, can calling me nonstop ! he is trying to meet up with me so i can do that stuff but I dont want to ! im so scared what if he finds me and he rapes me ! I in need help! Im to scared to tell my parents. recently I went to my friends and we walked to the park and we were hanging out and out of nowhere he pulls up and starts talking to me I was hella scared !!!! Im only 13 and he is 18 !! Help !
He actually sent it to people because I wouldnt do it !
The person he sent it to was one of my old best friends but she tolled he dad and he called the cops
