Warhol, sorry but you're an idiot if you don't report this guy.
Do you know what social engineering is? Because that is what this guy has done to you. The fact is, he seems like an awesome guy to you, because that's exactly what he is trying to do. He is trying (via social engineering, and personality mapping) to make you believe he is not a creeper. "But he isn't a creeper!", you say.
Yes, yes he is. He is 47, and you are 15. He is using what he knows of you to blind you from the reality. It's a very proficient way to do it, because you can't see it no matter what you do.
Get rid of him!!
