My Pretty Quadroon doesn't qualify. She didn't dump the guy, she died.

How about FOND AFFECTION?
   Refrain
The water is wide, I cannot pass over,
The sea so deep I cannot wade,
I'll just go hire me a little boatman,
To row me across the stormy tide.

I'll give you back your ring and letters,
And the picture I loved so well
And henceforth we will meet as strangers
But, I will never say farewell.

repeat refrain

There's only three things that I could wish for,
That is my coffin, shroud and grave,
And when I'm dead, please don't weep o're me
Or kiss the lips you once betrayed.

rep. ref.

this one used to tear me up good! especially the line about meeting as strangers.
Brett, my friend, time really does heal all wounds. If you want details, pm me.
