You didn't say if you are looking for lyrics strictly in folk songs. If not, there are a couple of old Detroit soul songs that riff on the paradox of loving someone the more he/she mistreats you:

AIN'T THAT PECULIAR (William "Smokey" Robinson/Marvin Tarplin/Robert Rogers/Warren Moore)
full lyrics at: http://gaye-marvin-lyrics.wonderlyrics.com/Ain't-That-Peculiar.html

Honey, you do me wrong but still, I'm crazy about you
Stay away too long and I can't do without you
Every chance you get, you seem to hurt me more and more
But each hurt makes my love stronger than before . . .

--------------------------------

YOU'VE REALLY GOT A HOLD ON ME (William "Smokey" Robinson)
full lyrics: http://www.thebeatlesongs.com/you_really_got_a_hold_on_me.htm

I don't like you
But I love you
See that I'm always
thinking of you
Oh, oh, oh,
you treat me badly
I love you madly
You've really got a hold on me . . .

Hope that helps.
