Player gets played

you're not what I expected, maybe that's why I'm so caught up
Was prepared to walk away, but now I just can't get enough
From barely interested, to feigning for another fix
How did you entangle me, when I thought I was slick
I meant to be the player, but got played along the line
Wham, bam, wait a minute, I thought you weren't that kind
I thought I knew the game, but you knew it better than me
I had the details worked out, but you went with simplicity
One girl plus one crush, is math even I can do
just one broken heart standing between you doing you
When one guy can make the world spin out of control
And one lie is all it took to break into someone's soul
There is no statistical data needed to see the plan in full
I was the fool, who let you in, so this isn't even cool
You hurt me, but I let you, oh sweet irony
My intentions were bad, but yours were also I see
