Why?

Why do you do this to me?
Why do you make me cry?
You know how I am feeling
Deep in my soul inside

You claim that you adore me
Yet play me day by day
And when my love comes shining through
You push my love away

You get jealous if I'm talking
To anyone but you
But when it's the other way around
You'll talk to me when you're through

I'm always on the back burner
You're affection's nothing but a lie
And when it is all said and done
I still just don't know why.
