Don't ask what am I gonna do   'Cause it hasn't even started sinking in   Need time, time to think it through   How am I supposed to know where I begin?      Suddenly, I'm alone here   Loving me isn't in your plans   Since yesterday, you were mine   And my heart was in your hands      Could've fooled me   Turned out I was wrong   You knew all along   That one day you'd be leaving      Could've fooled me   I was so secure   Confident and sure we were meant to be   You could've fooled me      So sad, I'm the last to know   Would have bet my life we were going all the way   It's too bad you didn't let me go   If you were honest then I'd be over you, today      Now suddenly, I'm alone here   To loving me, doesn't feel so right   Yesterday, you were mine   But we're history tonight      Could've fooled me   Turned out I was wrong   You knew all along   Someday you'd be leaving me      Could've fooled me   I was so secure   Confident and sure we were meant to be   Could've fooled me      There was no indication   No warning, no signs   I guess you could say that I   I must have been blind      Could've fooled me   Turned out I was wrong   You must've known all along   Someday you'd be leaving      Could've fooled me   I was so secure   Confident and sure we were meant to be   Could've fooled me      Could've fooled me   Turned out I was wrong   You knew all along      Could've fooled me   Turned out I was wrong   You must've known all along
