All Or Nothing

For once in my life, I know not what to do. Smart enough to say no, Yet, my heart, it beats for you. I know it all too well. This story's got a tragic end. But with you, it's all or nothing. So, a farewell I shall send. I want nothing but to have you. But fear has got its hold. I've never had a winning hand. It makes much more sense to fold. My stomach, full of knots. and shaking head to toe, I want you more than anything, but I've got to let you go.
