I have a friend I've met on the internet and have talked to for going on seven or eight years now. We have never met in person, but would I? In a heart beat.

Not everyone you meet on the internet is a "crazy" person, I mean, look at us PT-ers However, if you do meet someone and start chatting and you just get that bad gut-feeling, chances are just play it safe. I don't want to say write him off completely, as his ex could just be lying to you, but at the same time I would wait a long while before giving out any personal information.

And at the same time, talk with him, ask him point-blank about any doubts you may have, for example bring up "hey did you know your ex was on your accounts the other day? She said some pretty crazy stuff... is it true?". Because who knows, SHE could be the "crazy ex". She DID log into someone else's account that did not belong to her, which is wrong in the first place.

I just say, play it safe, and use your instincts. And if you DO decide to meet him in person, bring a friend or family member with you and do not have him stay at your house -- make it a day trip or something and where you are NEVER alone!
