I have to say... you are giving her way to much power.
If you are worries about not taking the bait, then don't take the bait! And if you choose to take the bait, what's she going to do? Divorce you?
From what I have read over the past few months, not talking to her about kid related stuff isn't really helping. It seems to me that it just builds the tension, increases the mindreading, and lets things get blown out of proportion.
