I met a guy at the beginning of the year. We became pretty good friends, I liked talking with him, he was nice, and it was fun. Then one day he asked for a picture of me, like, a normal one. I sent him one. After that, he started to ask me for pictures of me just in bra, or things like that. I said no, and he stopped asking me for a few days, before insisting again. I really didn't know what to do, and I wasn't expecting that at all. He was really cool, and in a second he just became an asshole. I thought maybe it was a joke or something, that he would go back to normal. He didn't. I finished by stop talking to him. I didn't answer his messages, because I thought that if I ignored him, he would get tired and stop texting me. After a few days, he stopped. But then, like, two or three weeks after that, a friend took my phone to text her parents and she accidentally called him. I took my phone back and hang up quickly, but it was too late. He started to text me again, to ask for photos. He insulted me, called me a slut, etc. I usually don't care when people insult me, I mean, it doesn't affect me, but I had spent the most awful summer of all my life, and it did make me really sensitive. So this time, the things he said to me affect me badly. I didn't answer. Even if I wanted to tell him to stop. I ignored him, hoping that he would get tired like the first time. I didn't talk to anyone about this, I was saying to myself "it's my problem, and in a few days it will be over". But this time he didn't stop after a week. He started to say that he would come at my home, and do.. Things to me. And I started to be afraid. So much that I didn't walk home alone, I didn't get out at all, and when I was home I closed everything. After two weeks I decided to block his number. I don't know why I didn't do this earlier. Maybe I was hoping he would become nice again. But he texted me by Snapchat and Instagram and told me that if I blocked him everywhere he would give my number to his friends. I wanted to change everything, my number, erase all my accounts, but I knew my parents would ask me why, and I didn't want them to know. And I am so so stupid for that. He stopped after two months, but even if he didn't talk or text me anymore, it was impossible for me to, like, move on and forget this. He made me completely paranoid. I don't know if we can call that bullying. I just needed to tell this, and it was the only place where I could do that.
