I don't know much about infidelity, but if you're not ready to lay your cards out on the table to her, then by all means, wait. You get one chance to "shock and awe", so do it when it feels right to you. It's obvious that whatever she's up to, it's got her head spinning trying to hide keep it covert. I might be inclined to sit back and watch her squirm for now.
