Having been online since before the visual web even existed (and been involved in two LDRs), I've seen this a lot with people. The basic answer is no. It's not a real relationship. It's a fantasy. And, frankly, speaking, maintaining a relationship w/ someone across the world is a near impossibility. Being in the presence of someone constantly is what forges a real bond. Doing the LDR thing, esp online, is a way to avoid a lot of uncomfortable things. Being present with someone and relating to them remotely are two completely different things. It's not healthy, especially at your age. You need to get out and explore people around you, IMO.
