I thought you knew 

When someone does something sneaky or stupid, then when they are caught say "I thought you knew." aka "I didn't think you needed to know"

Your girlfriend cheats on you with some guy, then weeks later says "I thought you knew"

I thought you knew 

heard in pockets of the southern US: an affirmation; agreement; inferrance of common knowledge... usually accompanied with a hair toss, whether or not there is hair to actually toss... expletives can be added to show emphasis or anger

"Everyone here wants to do you, Angie"
"I thought you knew, honey!"

"Donita knows not to mess wit yo man since you pulled her wig off and smacked her with yo heel!!"
"Thought you muthafuckin-GOTdamn knew!"
