I know how you must feel. Don't give up, no matter how slim your chances are!
3 Months ago I talked to a guy on Chatroulette till our connection got disconnected, sadly. All I was left with was his first name and the city he lived in. 5 weeks and a LOT of effort later I found him :-)
I hope this gives you a better feeling! You got it easy in comparison to me! Don't just go to the bar on the same day and time as when you met, hang out there more often :)
