Half Of A Whole

I'm just one half of a whole
Looking for my match
From the south to north pole
I'm in a rough patch
So hard it is to find
Something when you are blind
To how he looks and sounds
So far I haven't found
I know not his name or face
Yet in my heart is a place
Where he belongs to me
Yet I can't set him free
For what I have yet to learn
Is how not to swoon and yearn
For the one who fits with my
Puzzle piece, the apple of my eye
