what a girl/boy does before marriage is a different thing ... punjab is not as backward as u think ... with information and growth everyone wants to lifestyle shown on tv etc and most girls and boys in youth have some sort of mental relationship so this thing should not worry ... what should a person be worried is whats after marriage and one should make this thing clear ...
I m doing my masters now if i go for job next year i will be getting married if i decided to do Mtect i will be getting married may be after 3 years ... but i have accepted it and made my mind clear ... i m not worried what my future wife would be doing now ... in some relationship or drugs or whatever ... but after marraige she should be loyal, caring and list goes on ...
so its 21se century search a girl with an open mind no matter its punjab or uk ... dont accept to much or to less ... if ur good u will get a good wife ... if ur bad u will get a bad wife ... thats law of nature ...
best of luck
