Quandaries

I had an email exchange with a public person.

The person subsequently made it clear that he did not want the email exchange posted; I responded by assuring him that I wouldn't.

This creates some problems though:

• He thinks I'm making wrong inferences* from the exchange; presumably he'll say this to others. But the only evidence I could provide to counter his view is the evidence I've assured him I won't print.
  
  
• If he wanted, he ccould truthfully say he never asked me not to print it - since, literally, he didn't. But in order to show that this was what his writing conveyed, I'd need to give you the exact quote, which would be violating the privacy I said I'd uphold.

* This may be overstating the case; it's hard to tell.
