This says it all. You almost had it. But you never met, you never talked via phone or skype or anything else. You are obsessing over a 5 month, oh, I don't even know what to call it. It sure was not a "relationship" that you should be obsessing about.

Talk to other girls. Find someone local that you can have a real relationship with. You know, like actually being face to face with her? Going on dates? That kind of thing.
