Regret.

Why did he tell me
Every night that he loves me
But left me
I simply hate him

So I broke his heart
Made him cry
I regret it now
I'm sorry
I admit it
I was wrong
Now stop playing around
Take me back

I didn't mean to hurt you
I didn't mean to take your heart
You can have mine
I don't need it

Just don't ask for my sympathy
I don't know how to care anymore
Not when I feel prettiest
With tears running down my face

Why do I lose everything
And everyone I love
I must not hold on tight enough

I'm the one you're sworn to hate
But born to love.
