Myself a student of college.. M having a friend who was in relationship with a girl of different caste for almost two years. she was from a city.. They also had physical relationship. They even decided to marry in the future but due due some differwnce in compatibilties they broke up since 1 yr. .. later the girl blackmailed hum repeatedly to fulfill her demands..She even demanded for 5000 money.. If my friend pays her she wont interfer in his life so he even paid her. but still now she is controlling his life to whom he should make friends.. if he dosesnt listen to her.. she used to text his friends.. she even balckmails to call his parents blackmails of lodging FIR...
