Not Your Princess [acrostic]

Not the girl you always believed I'd be,
Or was I just the one that got away,
To you, maybe I was something special.

You actually believed this could last forever,
Oh, how naive can you actually be, darling?
Usually, I don't feel sorry for saps like you,
Really now, do you think I'm the marrying kind?

Probably letting the tears race down your cheeks,
Right now staring at all the words I said to you,
Is that moment actually replaying in your head?
Now that it's over, I must say you were fun,
Can you still think of me as your princess?
Each time I come to your mind, I hope you cry,
So, that you actually know you're still alive, hun,
So how does it feel to know I'm not your princess?
