Analysis of I'll never love Thee more

MY dear and only Love, I pray
  That little world of thee
Be govern'd by no other sway
  Than purest monarchy;
For if confusion have a part
  (Which virtuous souls abhor),
And hold a synod in thine heart,
  I'll never love thee more.

Like Alexander I will reign,
  And I will reign alone;
My thoughts did evermore disdain
  A rival on my throne.
He either fears his fate too much,
  Or his deserts are small,
That dares not put it to the touch,
  To gain or lose it all.

And in the empire of thine heart,
  Where I should solely be,
If others do pretend a part
  Or dare to vie with me,
Or if Committees thou erect,
  And go on such a score,
I'll laugh and sing at thy neglect,
  And never love thee more.

But if thou wilt prove faithful then,
  And constant of thy word,
I'll make thee glorious by my pen
  And famous by my sword;
I'll serve thee in such noble ways
  Was never heard before;
I'll crown and deck thee all with bays,
  And love thee more and more.
