Mansk, you have a crush. She is not a real girl to you at this point. You're projecting all your hopes and expectations onto her because of your loneliness and desire for a girlfriend in your life.
Have you seen pictures of this girl? Talked to her on a webcam? There are many missing pieces to this puzzle.
If you choose to pursue some kind of relationship with her, it will be very hard. There is the distance, your ages, lack of finances, and not to mention the fact that it's extremely hard to really get to know someone in a strictly online fashion. It's ok to stay in touch with her as a friend, but I would reel in your expectations about her as a real girlfriend for you...BIG TIME.
I'm not going to criticize you for your hobbies, but you deserve a girl who is going to be there for you in PERSON. There must be at least a few local girls who play WoW. And if not, you could always convert a local girl into a WoW player. I know a few girls who didn't play until their boyfriends introduced them to the game and then ended up loving it. Perhaps you're just afraid to go out and meet them? Rejection is a bitch.
But unfortunately online relationships can seem almost as lonely as being alone.
