Am I All That?

Ok, recently, this guy whom I met online who lives in New York but claims origination in my home state told me he wanted to come see me to go on a date. He claims that he will fly from NYC just because he is well off enough to do so and be content with dinter and a movie with little ol' me. Now...I know he's not a pedophile. But I do not know if he is a crazy, or a serial killer, or a psychopath. He alleges that he is a go-getter and he knows what he wants. He even mentioned that I just might be the guy that he'd marry. He got all this from a few pictures on my facebook account and a many conversation which mainly consisted of me asking him what the hell his problem was. It is a huge ego boost for me if this guy is serious, but it is also a check point for my mentals as well...and his mentals too. Is it really sane to offer such a thing? I mean...he had an answer for everything that i said. I didnt really have time to completely get my wits about me. Its very flattering but I just dont see why anyone would take that much of a risk to come see about me. Its something that romance novels have not even talked about. He said how can one find his soulmate without taking risks? Thats a good question. But is risk the same thing as absurdity? Is risk synonymous with delusional expectations? Hell if I know. I just had to get this off my chest.
