Actually, she does know. Just because you aren't articulating every instance to her doesn't mean she doesn't know. Who cares if you're snooping or you found out from the neighbors or whoever? YOU KNOW. That's enough. You don't have to prove anything. You don't have to play games.
You're trying to bend over backwards to disclose knowledge without signaling snooping? I feel like you're overthinking it.
