Need poem for parents

I want to find a poem that talks about the bonds of marriage, sort of like a 'tie that binds' theme. I want it to express that my parent's marriage has been an inspiration to their children and is the tie that binds our family together.

But I don't know of a poem like that. Any ideas?

Need help!

I love this:

Let not the marriage of true minds
Admit impediments, love is not love
Which alters when it alteration finds,
Or bends with the remover to remove.
O no! it is an ever-fixed mark,
That looks on tempests and is never shaken;
It is the star to every wand'ring bark,
Whose worth's unknown, although hiis 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 hours and weeks,
But bears it out even to the edge of doom:
If this be error and upon me proved,
I never writ, nor no man ever loved.


William Shakespeare


I'm going to use it. I hope you like it.
