Want to live for you

Girl-am I pretty?
Girl-do you want to marry me?
Girl-will you cry if I leave you?
Boy-no. The girl got vexed
and started to cry.
The boy pulled her close to him
and said you are not pretty but prettiest,
I don't want to live with you
but I live for you,
if you leave me
I won't cry but I die.
