Should I meet up with him?

So there's this guy that I met online. I randomly added him from somewhere on facebook cause I thought he was cute. This was last year in august. He's from melbourne and I'm british-algerian. Then we started talking on msn and I got to know him even better. So we talked and talked. We talked very often, and he told me about his life and his problems and everything and we sorta became really close online friends. Sorta like pen-pals kinda. (: And I got to know his twin bro from there too. And then we started webcamming. And we talked there, and he played piano for me and I sang and played the guitar for him. He's a really cool guy, and I'd really wanna meet him in the future if it's possible. I'm 17 and he's 15. He wants to come and see me when he's 18. I think it's a good idea. And well, there's more to it.. I kinda like him and he likes me. that's why we pretty much want to meet up. what do you think? should we?
