‘I'm sorry' you say. I must ask for what?
  For not being an angel?
    Don't be for you are my guardian angel.
  For not being perfect?
    Don't be for I see no flaws.
  For not telling me you love me enough?
    Don't be for everything about you tells me you love me.
So, I must ask again my love, for what are you sorry for? I love you just the way you are.
