Have You Ever Been In A Serious Online Relationship?

My question(s): Have you ever been in a serious relationship with someone you had (originally) met online? What tips would you give for making one work?
My story: I’m 15, my girlfriend is 13 & 1/2. We’ve been going out since June 3rd 2009. I met her on an online game about 6 months ago. Ever since I met her I’ve been crazy about her. She’s funny, VERY pretty, sweet. And I know she’s not some old pervert – I’ve seen her on webcam before . She’s not comfortable with dating guys in real life… She really likes me, and I really like her. But the sad thing is we’ll probably never meet as we’re young and she lives 720 miles away. It really depresses me because I love her so much and she’s so beautiful and unique… Although I feel I’m not being fair to her because she’s in public school where she lives and she says she gets asked out by guys alot. She says she tells them no because she loves me. although again, I feel we’ll probably never meet. And if we do it’ll be way in the future. I’m home schooled, and thus I have no real life friends. I would normally never date online like this for obvious reasons but I’ve grown so close to her so fast. She’s anything I could ever dream for. I’m just trying to find a way to better make this relationship work. Something to make us feel closer (in distance). I don’t have a cell phone (strict parents) so I can’t call her. I feel like if I ask her to go on cam I’m bothering her cause she most likely doesn’t want to most of the time … I really trust her, and I really love her. I really want it to work. But IM conversations are getting boring…we’re BOTH running out of things to say! I don’t want to let her go. How can I keep from losing her, I really don’t want us drifting apart/losing interest in eachother because we really have something. She’s my dream girl
Advice please!
Thx,
Jason.
