A message to a heartstealer

Oh I girl I know just all everything,
There is to know about your little game.
Thought you were a nice girl,
Held you in high esteem,
That's why its such a shame,

So you think you have me wrapped round your little finger,
Playing me like a puppet on a string,
You've got all the people I know believing your side of the story,
And singing along to your "he wont leave me alone" song that you sing,

I laugh at the fact that you were just that smart enough,
To see my heart is highly protected,
The threat you opposed to my heart was already detected,

As far as I am concerned you can keeping it coming with the drama,
Because I'll win in the end,
What goes around comes darling is what it's all about,
Look it up in the dictionary it comes under karma,

You asumed I was a butter wouldnt melt good boy,
And tryed to exploite my vunrabilitys,
But protection from heartbreakers and trouble causers like you,
Is one of my many specialitys,

Think before you try and push me into the danger zone,
I have seen my fair share of party spoling bunny boiliers,
So for your own saftey stare clear of me,
When I wash you out of my hair,
You had better leave me alone,
