Mary, you don't know how much you mean to me If you did, you'd never ever make me feel this way Mary, you don't know how much you care for me If you did, I'd know you wouldn't make me hurt this way Now I realize you may not feel the same for me Or are you trying to hide how much you care Have you thought about how hard this is for me To live in this one-sided love affair Mary, you don't know how much I feel for you If you did, I know you wouldn't hurt me this way For you have to know I care, baby Cause everything I've ever said or done Should let you know that you're the one Now you have to know you're more than juast a friend to me Are you using me or are you just gone aware Mary, can't you see that this is hard for me To live in one-sided love affair Now you know that in your heart You feel the same baby You're just trying to hide how much you care Oh, let me in your heart or just let me be But put an end to this one-sided love affair
