I know it's sappy but it was first thing that came to mind :-)

My Emily Dearest

To say what I must to say what I may.
She's the air I breathe and the brightness of day.
To look in her eyes when I will call her my wife.
I hope that I keep her till the end of my life.

If we fight and we fuss it's all for the best.
I can't help but think, that it's only a test.
The sweetness of her voice and the strength of her soul.
Carries me through, makes half of me whole.

When my vision is blurry,
she helps me see clearest.
She's the angel in my sky,
My Emily dearest.
