David's Looking for a New Co-Host

Hi, my name's Lena. I normally make friends online. I do have a social life outside the internet, but mostly I spend my time with internet friends. Anyway, I made friends with a guy who's 4 years older than me. I am 14. Huh. He's a really good friend of mine and I want us to stay good friends. However, a few days ago, after we became friends, he started to talk very sexually to me and I shook it off as I thought of it as a normal thing. He began to become more and more sexual and he confessed to me that he loves me. What the fuck? I don't like him back and I keep telling him to stop, but he wouldn't. I stopped talking to him once, but I gave into temptation and started talking to him again. He would tell me he loves me every time we talk, so I did a prank on him where I told him I was with one of our friends. It backfired. He began getting depressed and left me on read.
