Not long ago we loved each other
And we were as happy as can be
Now you are happy with another
I suppose that you've forgotten me

I am the one that you fooled yesterday
Whose heart are you breaking now?
You took our romance and threw it away
Whose heart are you breaking now?

What has become of the love I once knew
What have you done with each vow?
Somebody else is a king for a day
Whose heart are you breaking now?

I am the one you left all alone
Whose heart are you breaking now?
You are the one with a heart made of stone
Whose heart are you breaking now?

I used to think you would always be mine
But everything's different now
You're laughing now but someday you'll atone
Whose heart are you breaking now?
