I moved to Karachi

Maybe we, at least I am misunderstanding you, and I apologize for that.

If you are looking to date a girl in Karachi, I guess the most decent way of doing it would be to socialize with your family and naturally run into a girl who would like to know you as well. Somehow meeting strangers gives a wrong impression of your intentions. The kind of girls who are so easily available in special places aren't really looking for longeterm relationships and I'm sure you are wise enough to know that. Our culture is such that girls from good families and/or values like to protect their reputations and don't like to be "set up" for "dating"... at least that is how it was a few years ago...
