I know you're asleep but

Something a guy texts a woman at 3am, when he's most emotionally vulnerable so he can vent without fear of being judged

"I know you're asleep but I just wanted you to know that I love you lots, and I couldn't live without you"

I Know You Know I Know

Unspoken information between two parties where both are aware that the other party is aware of a hidden truth, secret, or hidden agenda.

I know the information you exposed isn't true, and more importantly, I Know You Know I Know so maybe it’s time to stop the act.
