One Direction

Now that you can't have me
You suddenly want me
Now that i'm with somebody else
You tell me you love me
I slept on your doorstep
Begging for one chance
Now that I finally moved on
You say that you miss all alone
Who do you think you are
Who do you think I am
You only loved to see me breaking
You only want me cause I'm taken
You don't really want my heart
No, you just like to know you can
You'll be the one who gets it breaking
You only want me when i'm taken
You're messing with my head
Girl that's what you do best
Saying there's nothing you won't do
To get me to say it
You're impossible to resist
But I wouldn't bet your heart on it
It's like i'm finally awake
And you're just a beautiful mistake
Who do you think you are
