Dude, he just sent you 100$, gather evidence and blackmail his ass. Discretely ask for pictures, play along with his bullshit but don't reveal anything about yourself. Have you clicked on any dodgy links that he has sent you? Watch it, because it could be an IP finder site, and he could know where you live. But yeah, give him back the 100$ and say you need more time. If you give back the 100$, he will either do one of these two things: He will tell you to keep it, and trust you, or he'll take it and trust you for giving it back. If you gain his trust, you can skillfully play him and then black-mail his ass, demanding around 2000-3000$, which would be nothing if the guy was rich and had the risk of getting thrown in jail for 6 years. Try to get more evidence. Get his Skype and do a webcam session with him, recording it, and if he starts getting freaky, get it all on tape and then say you're not ready for this an act really emotionally unstable. This is a fucking great opportunity right infront of you man!
