I've met two people that I met online.
The first one I really shouldn't have gone to visit. Nothing bad happened, it was just not the best idea. I haven't talked to him since I visited. Which is for the best really.
The second person I've gone out to visit twice. Met him in a chat room nearly 3 years ago now. We chatted nearly every day for quite awhile, we don't as much now since we're both more busy with our own lives. But we still chat a few times a week. I think he's a fantastic person, one of my best friends. If I lived where he lives I'd want more in terms of a relationship, and we've talked about that recently. But I don't live there so at the moment there really isn't anything to discuss.
As far as people from TFP goes, well, I'll be meeting somebody in a month
I'll be out in his area in a month for a concert and he's offered to take me out on the town. I figure why not? Right now I'm still getting to know him but he seems like a really nice guy.
As far as a romantic relationship with somebody online, I don't think I could do it. Because it would mean having a long distance relationship and I won't put myself through that again.
