All I've seen so far is an e-mail from Buckley to Arator stating that you were advised of the potential costs of the FR vs. Eschoir suit, and referring to other e-mails Buckley sent to you without quoting them. The e-mail to Arator closed with Buckley saying, "You can quote me on that."
I can't believe Buckley would actually disclose info that a client wants to be kept confidential, and I don't think that's what has happened here. Of course, if the client denies that his attorney advised him about a particular fact, the attorney would then have every right to set the record straight.
Like I said: I think Buckley advised you at one point that the bill could go as high as $75K - $100K, and you probably read and deleted that e-mail at about 3:30 AM with about 100 other e-mails. The sigificance of that message did not register at the time.
This is how disagreements arise. People who work too hard, too late at night, may miss a detail or two. This description fits all three of us. And that's what a paid staff would be for: keeping track of the details.
