Envy

I once loved what once was love
But now is bitter hate
Though what once was love was surely love
But was on a bumpy slate

But once my love loved me no longer
I felt deeply empty inside
As my love's love for her grew stronger
I felt that I wanted to cry

Though my love you'll surely see
That I'm dangerous and sly
I'm overcome with sick envy 
My love she'll surely die
