I like the line...
"Just three words
Is all it takes
For you to steal
My breath away."
A lot of people say take my breath away I like steal my breath away, very nice!
Also I think you could organize it stanza by stanza it might be easier to read like this:
Just three words
Is all it takes
For you to steal
My breath away.
Just three words
That brings both pain
And endless happiness
To my life each day.
Just three words
And I go weak
My heart melting
With every beat.
Just three words
Wrapped with my life
Sparking the flames
That grows in my eyes.
Just three words
Coming from the heart
To show that I love
Thats the greatest part.
Just three words
Is all it takes
For you to take
My heart and soul away.
