How can the Heart forget her?

AT her fair hands how have I grace entreated
With prayers oft repeated!
Yet still my love is thwarted:
Heart, let her go, for she'll not be converted
      Say, shall she go?
      O no, no, no, no, no!
She is most fair, though she be marble-hearted.

How often have my sighs declared my anguish,
Wherein I daily languish!
Yet still she doth procure it:
Heart, let her go, for I can not endure it
      Say, shall she go?
      O no, no, no, no, no!
She gave the wound, and she alone must cure it.

But shall I still a true affection owe her,
Which prayers, sighs, tears do show her,
And shall she still disdain me?
Heart, let her go, if they no grace can gain me
      Say, shall she go?
      O no, no, no, no, no!
She made me hers, and hers she will retain me.

But if the love that hath and still doth burn me
No love at length return me,
Out of my thoughts I'll set her:
Heart, let her go, O heart I pray thee, let her!
      Say, shall she go?
      O no, no, no, no, no!
Fix'd in the heart, how can the heart forget her?
