In spite of the stigma that's usually given to long-distance relationships, especially those initiated over the internet, I really don't think they're half as bad as some people might make them out to be. They do, however, have their own set of problems.
One of the biggest issues, of course, is distance. With today's technology, it's possible for two people to meet from literally anywhere in the world. In today's society, however, mobility is higher than it has ever been. You can fly across the country for next to nothing, & moving can be accomplished with relative ease. But... The interim sucks. You'll want nothing more than to be with the person, to be a part of their day to day life. But you can't be. That's probably the roughest part right there: You'll miss them like crazy.
The other thing that people seem to worry about is the danger... What if they're not really what they say they are? Be careful. A visit or two should confirm who they are, though. Any glaring differences between their online perona & their "real life" counterpart should raise some warning flags.
As long as you're aware of the shortcomings, though, long-distance relationships do have advantages.
First, the relationship is just that - A relationship. It's impossible to go out & spend non-personal time (movies, concerts, etc) together. Everything is based on communication, there's no avoiding it. That's all you have. Which is really nice sometimes. You'll get to know someone very quickly, & if the communication ever breaks down the relationship does too. You'll never be stuck in a relationship with no communication.
Another advantage is the lack of physical temptation. Obviously that doesn't apply to everyone, but it's very hard to mess up physically if you're thousands of miles away. So if you're trying to save yourself for marriage, the distance can be a big help. Be careful, though, when you ARE with them, 'cause you won't be used to having the temptation AND the ability to act on it.
Anyway, those are my thoughts. As you probably know, I'm in a long-distance relationship too. At times it sucks, since I want nothing more than to be able to hold her when she's crying, take her out for dinner when she needs encouragement, & stay up all night watching movies on the couch. But she's still my best friend, & I wouldn't trade it for the world.
Good luck.
