I don't argue that meeting isn't a necessity - it is. In a relationship where one of the two people is unwilling or unable to meet the other, there is clearly a problem in the relationship (if, in this case, it could be called a relationship.) I do think that it is possible to have a relationship that is solely online, but that for actual love, there needs to be an intent to meet. But I also feel that it is possible not just to fall in love, but to be in love, through long distances. It takes hard work, and it takes two people who are honest, communicative, and devoted to one another.
I've seen long distance relationships fail, but I've also seen many suceed. I think that part of why love can be so hard to find at a distance is because of the ease of a fantasy life, which has been spoken about in length on this thread. It is easier to lie to a person, it is easier to make yourself seem to be someone that you are not. It's easy to shield a person from the negative sides of you when it's as easy as flipping a switch. But these things don't make all long-distance relationships invalid.
There are actually benefits to beginning a relationship on the internet. The same anonymity that makes it so easy to lie to someone also makes it easier to open up. It makes it easier to tell the truth, because it's easier to run away if someone doesn't like you. The relative emotional safety provided by the internet can make people grow closer, faster. And the emotional closeness provided by the internet, while often misplaced, can be a wonderful thing. Eventually the safety crutches go away as the relationship becomes more intimate, as more personal information is shared. I knew that something had changed the day I realized that I didn't have an online relationship - I had a real relationship with a real person, and the internet just happened to be the way we communicated.
However, I will accept that my situation is most likely a rarity. The first time we met, it was intented to be romantic - and it was an experience that we both enjoyed a great amount. I do have to take into account that we were unusually close and acquainted with one another - having spent approximately six hours talking a day for nearly a year. We'd talked at length about meeting, and our expectations from it. We went into the meeting expecting no change in our relationship - we didn't expect it to miraculously bring us closer together, or to drive us apart. And as I stated before, the only difference was the physical.
Because of my positive experience, it does bother me when I read or hear negative (blanket) statements about long distance relationships, because it feels as if others are invalidating what I and so many others have found to be valid, healthy, and lasting relationships. That's not to say that I can't deal with it, or that it's emotionally upsetting - just that I feel the need to present the other side of the argumenet. I fell in love over the internet. I stayed in love, still over the internet. And I'm not the only one.
