It doesn't sound real kosher, but you could give him minimal info and see if he responds. Remember, most of our info is out there in cyberland. Creepy, but it is. Just be careful and I know you know not to meet anyone without someone with you. And if you ever feel uncomfortable giving out your information or meeting up, then don't do it. It's as simple as that. Your gut knows. And if your gut is wrong, so what?! You're safe and that's all that matters.
