Realize What You Have Before You Lose It

I forgave you,
You burned me all over again.
I did everything you asked,
You took me for advantage.
I cherished your every move,
You lead me around like a dog.
I helped you with all of your problems,
You ignored me and all mine.
I fell 'head over heels' in love with you,
You left me alone in the dust.
I finally walked away,
You finally realized I meant something.
You want me back,
I'm gone forever.
