The virtual world is, like its name states, virtual.
A long distance relationship is already difficult enough. What's
more is a relationship stemmed from online.
It is not impossible. Definitely not impossible. But it is highly,
highly difficult. A relationship needs that physical touch. That
hug, that kiss, that holding of hands.
A long distance relationship lacks that.
But by all means, go for it!
Good luck. =]
