Keeps on defeating me. it just keeps on defeating me.. [Chorus:]. So what I'm trying to say I know what's happening. Your body is here with me. But your heart and your mind is still with him.. Go back to what you know. Go back to where you know where your heart is. Girl just be honest this is impossible. This is impossible we'll never work cause you don't. want it.
