rolan, are you interested in getting to know this person? I personally don't think finding out on Facebook is all that bad, but please try not to get obsessed with tracking her every move.

Other folks might disagree with me, but I think it would be okay to find out where to go to meet her. And then do so, to see if she is interested in you. If she is not, then let it go. Otherwise, I think you would be getting into creepy stuff.
