Slave to what?

My friends, I tell you no lie,
There once was one stronger than I:
She wore scarlet, crushed velvet and silk.
Her smooth, perfect skin white as milk.
She met a lad in her early years,
He told her all he'd have her hear;
Sweet words and caresses every day,
Putting on quite the display.
Gifts abound, adventures galore!
She knew him as her saviour.
Possession! Possession!
A demon inside!
A demon hath made her his bride.
No touches to please-
It's only greed.
Locks her away...
Such easy prey!
Love slave tonight,
Tomorrow- out of sight.
This is now me.
How could I not see...
He was deceitful,
Yet I get an earful.
Now weak and broken,
My pillow dampened,
Skin now aged,
Easily upstaged,
Clothes are rags,
Under-eyes bags.
But yet I stay,
I dare not stray.
I'm not deranged,
Some day he'll change.
