I'm Not The One, But she is

I'm not crazy
But I'm crazy for you

I'm not an addict
But your the drug I'm addicted to

I'm not a stalker
But you may think I'm one

I'm not your sister
But sadly you treat me as such

I'm not your pet
But in your mind you think I am

I'm not your first choice
But deep down i wish i was

I'm not the one begging on knees
Like she is

I'm not making your life a living hell
But she is

I'm not the one cheating on you with your friends
But she is

I'm the one you can count on
When you feel alone

I'm the one you come to for advice
When you got no one else

So just answer me this
How come... How come

I'm not the one....

You love?
