What happened?

You keep running through my head
Cuz I don't know what I did or what I said
For you to push yourself away
It felt like a game we always had to play
You never got to know the real, true me
and I know if you did, you'd realize and see
You'll never meet a girl to compare or take my place
I know you almost felt that way, I could see it in your face
It seemed so perfect, and the next day it was gone
I really need to let go cuz I did nothing wrong
Then I start to think of your smile and how I always felt
Then it's your eyes and touch that always made me melt
I was warned your reputation
I really need to let go
It hurts to think what we could've been but
I guess I'll never know
