Did I Just Go Crazy?

Did I just go crazy?
Why am I falling for you?
You're nothing that I want, I need,
For you I have no use.

But your constantly in my head,
Floating around in my mind,
Being the little selfish prick you are,
Taking up all of my time.

I can't think right,
You're blocking my view,
I keep telling myself,
That I don't love you.

So why are you here?
Haunting all my thoughts,
Ever since I first met you
It was only pain you brought.

Yet you keep making me smile,
With all the jokes you tell,
And every second I love you more,
Even when you yell.
