You are 21 years old and can take decisions of your life.  But how sure are you about that boy whom you love and how serious is he to have you in his life. Are you guys truly in love or just an attraction, first analyse that part. Parents do have responsibility to get their daughter married and give her safe and secured life.  However understanding your feelings and expectations are also equally important. This is a catch 22 situation. If The boy is genuine, he should talk to his parents and take further steps to meet your parents. Caste is not a criteria for happy marriage. Talk to your parents and convince them, if your love is genuine and serious. Dont take any hasty decision. Marriage must bring two families together and not just 2 individuals
