You're the one

You're the one I think about
When my mind goes astray
You're the one who fills me out
Every moment of the day.
You're the piece that fits the puzzle
The little wheel on my engine
You're the reason for survival
Far beyond what I imagined.
You're the handle I'm attached to
To keep me from get insane
And for everything you do
I thank you and call your name.
Every since you catch my eye
With that warm and tender look
I could no longer deny
That my heart, you really took!
