I thought I told you, he'd be home soon Couldn't help myself, you're too good to be true. I fall short each time, Every time he ain't here You and your charm creep closer Closer in here Like a fool for fire I fall, with my pride and all. Like a bomb before explosion, Ticking by your call, You're the wiser one, disguised from greed, And I'm just a child who belongs on her knees.
But I found a boy who I love more, Than I ever did you before, So stand beside the river I cried, And lay yourself down. Look how you want me now that I don't need you.
So, you thought that I'd crumble to my knees At the first sight of you crawling back to me To whisper "will you leave your man? " You sweared that this time you can stand by me. I won't stand by you.
Cause I found a boy who I love more, Than I ever did you before, So stand beside the river I cried And lay yourself down. Look how you want me now that I don't need you!
I ain't yours for no taking, You must be mistaken I could never look into your eyes, and settle for wrong And ignore the right
Well I found a boy who loves me more, Than you ever did me before. So stand beside the river you cried And let yourself down! Look how you want me now that I don't need you!
