There's the old forlorn cowboy classic:

You've stole my wife, you horse thief!

Then there's the abridged version of "Don't Think Twice" which is called "Don't Think Once."

And then there's the old time song called:

LONG GONE
(Anon from singing of Jennifer Puleston)

I remember well the day I met you
With your smile so fair and bright
And I loved you from that moment
'Til I met you here tonight.

Chorus:

Long gone, that's how I'm leavin',
Long gone, why do you cry?
This is what you've always wanted,
Yes, I'm gone, long gone!

I've tried my best to make you happy,
Still you say I've done you wrong;
So I'm giving up, my darling,
And I'll be gone, long gone.

Do not try to overtake me,
What I ride will be too fast;
All my bags are packed to travel,
Long gone, long gone at last.

When I see you try to spite me,
When I see you turn away,
All the grief that I've been feelin'
Tells me there's no other way.

It would of been better for us, my darling,
If in this world we'd never met;
For though I loved you like no other,
Now I'm goin', I've just regret.

A little long but, hey, this is theraputic!
