I'm the Only One - Melissa Ethridge

In this song, the woman is miserable that she's been left behind. She tries to show the guy that nobody else could ever possibly love him the way she does. Especially not the trollop he's with right now!

I'm the only one to walk across the fire for you
I'm the only one who'll drown in my desire for you
It's only fear that makes you run,
the demons that you're hiding from
when all your promises are gone
I'm the only one.
