Y U No Marry?

Most of the love stories in India ends in the similar fashion as drawn in below diagram (drawn by me :) ). I have seen the stories like these where girls and boys fall in love with each other but could not get marry. They very easily sacrifice their love for the sake of their parents or society. What really hurts is to see that even they don't mind happening this to them. They let their love and memories go very easily. They don't fight, instead they compromise. This compromise indirectly means they agree to things that once became hindrance in their way to marriage. They accept that religion, caste or money comes above the love they use to share. They prefer to let go, accept defeat and move on. I understand that sometimes you need to make sacrifice but you should make them when they are really worth to make.
