Do you think it is wrong to be really good friends with someone that your never going to meet in reality?

Not wrong. I'm mostly fine or just neutral towards this. But if the friendship becomes exceedingly close to a certain point, I will find it quite odd. :/

I have a wonderful friend who I've never met in real life. I met her on Neopets when we were 13 and now we're friends on facebook. We video blog and sing songs to each other and tell each other our problems. I talked to her when she was suicidal and she helped me when I was depressed.

I was super cautious about giving her information, so she doesn't know my address, but she has my phone number and knows the city I live in.

For you, you may have made a mistake, but it's too late to do anything about it other than be super careful in the future. Keep your wits about you and maybe tell your parents that you're a bit worried about what you've done.

no its good to have friends your never going to meet...

I had an online friend for a while in high school. We talked on the phone sometimes, but mostly on AIM and Myspace (it was back in those days). I think you need to be careful though. I would advise not to give your address, though I did give my friend mine so he could mail me a letter (probably not the smartest idea).

Outside of safety I don't think there's anything wrong with it! It's fun to meet someone different from you and to have a friend you can confide in that really doesn't know anyone else you do.
