Got it. I just thought there might be more of a hint as to how much I know. No problem.
If you want to go that route, I would ONLY say "I know all about..." or "I know everything."
There is great power in them not knowing what you know, what you DON'T know, and then therefore they have to assume you know EVERYTHING.
That's why you NEVER reveal the source(s) of your intel, and you NEVER go into any more specifics than you have to. I have even gone so far as to purposely divert them, by saying "I promised someone I wouldn't reveal their confidence, and I'm going to live up to that," when the only source of intel was an inanimate object like a keylogger or a voice recorder. Then you watch the wayward's head spin, as they -- in their paranoia -- try to think of EVERYONE who may have ratted them out . . . including their affair partner!!
