Can it be legit?

Well, theres this girl I seem to be going crazy over, the problem is, she lives in Colombia, lol. We met off Facebook. Just as a "rule of thumb" of a sort, I typically never ever ever take anything seriously if its long distance and we havent been together in person yet, Im probably one of the most skeptical people youll find off that type of relationship. But this girl is incredibly beautiful and probably the sweetest in the world. We've talked a lot and we are "together", but I cant help but be skeptical. I know it is really her because most of the time when we talk she's on webcam. She even says she'll be coming here in December after she graduates from college....Im getting so happy because when we talk it feels like it is a real relationship, and I love everything about her....but its so hard to believe something that seems so great can be legit. The only way to be sure is to wait until December and see what happens, but what are your thoughts?
