It's a sin my darling how I love you Because I know our love can never be It's a sin to keep this mem'ry of you When silence proves that you've forgotten me The dream I built for us has tumbled Each promise broken like my heart It's a sin my darling how I love you So much in love and yet so far apart [ vibes - steel ] I'm sure you're happy with another Who shares the love I couldn't win Why pretend that I can't live without you When deep inside I know that it's a sin
