Am I just what you make of me? Do I not have a say? I know that you're just make believe But I can't stay away Here I am now dreaming without you If it's you I can't follow, where do I go? 'Cause I'm just an extension of you Don't know who I'll be when we are through I am who you are Until we fall apart I'm part of you Until you're just someone I knew And I can't help but fantasize About who I was before (before you) But I can hardly recognize The me behind closed doors (closed doors) I never thought I'd be dreaming without you I can't move on if you're all I know 'Cause I'm just an extension of you Don't know who I'll be when we are through I am who you are Until we fall apart I'm part of you Until you're just someone I knew (Someone I knew) (Someone I knew) (You were just somebody I knew) (Someone I knew) Someone I knew (Someone I knew) Until you're just someone I knew (You were just somebody I knew) (Someone I knew) Someone I knew (Someone I knew) Someone I knew (You were just somebody I knew) (Someone I knew) Someone I knew (Someone I knew) Someone I knew (You were just somebody I knew) 'Cause I'm just an extension of you Don't know who I'll be when we are through I am who you are Until we fall apart It's a shot in the dark For you to break my heart I am who you are Until we fall apart I'm part of you Until you're just someone I knew I'm part of you Until you're just someone I knew
