If you leave me I'll die. A sad love story!

One night a girl and her boy were sitting in a car. There was a complete silence, both of them stayed quiet for long, then the boy gave her a chit of paper. Before reading it, the girl told the boy (with embarrassing expression) that she wants to leave him. Then suddenly an overspeeding car collided with their car. The boy died and the girl somehow survived and when she opened the chit (which was in her purse), she dropped tears bcoz the boy had written only one line on it which was "if u leave me i'll die".
