What good does true love do? Why'd I fall in love with you? You can break a promise but You can't break my heart. If I can't change your mind. You go your way and I'll go mine. You can't tear my world apart. You can't break my heart. Who do you think you are? Walking out on me now. You might leave a little scar. Now I have nothing left. Only heartache and regret. You can break a promise but You can't break my heart. Who do you think you are? Walking out on me now. You might leave a little scar. But you can't break my heart You don't know where to start. You can break a promise but. You can't break my heart.
