Analysis of Fair Iris I Love and Hourly I Die

Fair Iris I love and hourly I die,
   But not for a lip nor a languishing eye:
   She's fickle and false, and there I agree;
   For I am as false and as fickle as she:
   We neither believe what either can say;
   And, neither believing, we neither betray.

'Tis civil to swear and say things, of course;
   We mean not the taking for better or worse.
   When present we love, when absent agree;
  I think not of Iris, nor Iris of me:
  The legend of love no couple can find
  So easy to part, or so equally join'd.
