I thought you knew   I guess I assumed too much   I don't know how but now we're so far out of touch      And I never planned to so misunderstand   But what you needed you never asked me to give   And I swear as I live      I thought you knew my heart was yours   And that we were so together, that we would always be   I don't believe you leaving me's the answer      I'm not asking you to let me rush back in and fail again   I'm asking for one chance not to assume   So I can say and do all the things I thought you knew      So here we are and so far we're still so far   From where we know we should be   I'm searching for words and you haven't heard      I thought you knew my heart was yours   And that we were so together, that we would always be   I don't believe you leaving me's the answer      I'm not asking you to let me rush back in and fail again   I'm asking for one chance not to assume   So I can say and do all the things I thought you knew      I thought you knew   Oh, God I thought you knew
