I've had so many people telling me horror stories from internet dating that I've just stayed away. Ironically, I've had at least one relationship that while it ended... (lets just say it ran it's course,) it wasn't horrible. We kind of fell into it, though, as friends then more.
The current relationship started more intentionally so- but it still started as "I like you as a friend, maybe more, lets see where it goes," kind of thing.
