Know Exactly

You forced me to do this
When you walked out the door
You acted as if nothing happened
When I caught you with her
You say that you love me
When I start to cry
You start to hug me
When I say I'm gonna leave
You grab my arm
When I turn to walk away
You say that I am joking
When I say I'm serious
You will never know the truth
When I see you
You will never get a clue
When I say I hate you
You try to understand why I left
When I know you know exactly why I left
