Let Me Not To the Marriage Of...

Let me not to the marriage of true minds
Admit impediments. Love is not love
Which alters when it alternations finds,
Or bends with the remover to remove:
O no; it is an ever-fixed mark,
That looks at tempests, and is never shaken;
It is the star to every wandering bark,
Whose worth’s unknown, although his height be taken,
Love’s not Time’s fool, though rosy lips and cheeks
Within his bending sickle’s compass come;
Love alters not with his brief hour and weeks,
But bears it out even to the edge of doom.
If this be error, and upon me prov’d, 
 I never writ, nor no man ever lov’d.
