Get Yourself Another Fool by Sam Cooke.

"Get Yourself Another Fool"

At last I've awakened to see what you've done.
What can I do but pack up and run.
Now I know the rules. Get yourself another fool.
You said that you loved me. I was yours to command.
But your kind of loving, my heart couldn't stand.
You used me for a tool. Get yourself another fool.
And now, now that we're through, you say you meant to be true.
Oh, but deep down in your heart, I know our love could never grow.

I tried to believe you that we’d never part but your love broke my poor heart.

Now I know the rules. Get yourself another fool.
Get yourself another fool.
