The idea behind this poem is really good. i would suggest you remove those capital letters at the end of each sentence because they are taking away the flow of the poem. use commas instead and full stops but where necessary.

here is my suggestion

I am one half,
you are the other.
Together,
we make perfect lovers.
I am the jig,
you are the saw.
Together,
will make this love puzzle grow
One day,
the puzzle will be complete,
then we will relax
and put up our feet

I have just tried putting in the commas and full stops where necessary. i felt the last part about feet doesnt do it for me, it was like you were looking for a rhyming word. I give it a 5 because i know it could have been better.(hope am not harch)

Thats good. Well written x

Thanks.love you.xx
