You are looking for 'Green Eyes' by the sublime Kate Wolf:

GREEN EYES
(Kate Wolf)

Every night we light the candle
That stands beside our bed
But sometimes the flame's too much to handle
That's what you said.
That's what you said
And you should know
Because you built a fire in me and you made it burn
You followed me, watching every move,
Matching every turn.

Chorus:
Your green eyes they don't miss a thing
They hold me like the sun going down
Warm me like a fire in the night, without a sound

You were waiting till I heard
Just as patient as that love light in your eyes
You never threw away a word,
Or ever talked in a disguise
I ought to know
You were a beacon to a sailor lost at sea
I saw it in your eyes
When you looked at me
So openly.

chorus

The first time I ever saw your laughter
Break loose inside and tumble out to me
My heart knew it had found what it was after
And it came so easily
We should know
After all the years of the hard and heavy times
Now our days go by like best friends' story lines
Yours and mine

chorus

--Stewie.
