Let Me Go

You say you want me, you say you need me, but when I touch you you're like wet soap in my hands. And when we go out, you can't speak out loud, you're afraid someone might hear you call me dear.
Does it make you happy, if I'm sad and crappy, do you get your kicks from hurting me? If you want to have me, you gotta have all that is in me or just let me go.
You never introduce me to the people we meet, if someone asks, I am your cousin or a friend. And when I call you just to say I love you, why you have to whisper back I love you too bye bye.
