Love stories that didn't end well

This is a legendry pair whose love story has all the elements of a Classic. The most successful actor, Amitabh Bachchan with the most desirable heroine of the screen, Rekha. They were meant to be separated as Amitabh was a happily married man. But the lump in the throat of the fans because of this vulnerability makes this love story immortal. They are aging but even then small news of their just passing by each other, leave looking or talking to each other, makes the media manic. Such is the magic of this pair..
