Leaving together before marriage isnot permitted in the Indian society. It is forcefully burrowed from the wetern culture and shouldn't be allowed in any case. It is taking the shape of a passion for the young generation and they take it as license for premarital sex. To understand each other sex couldn't be thought of a criteria anyway. We should remember that we are recognized and respected as Indians because of our unique culture and we willn't let it go just to copy other culture.
