Hang in there drained,
I would bet my house that he is manipulating you and will sign those papers but at the very last minute. It also sounds like he is a Spin Doctor in bringing up the issue with his secretary and taking the focus off his drug use. Besides his ego isn't going to allow him to go into a trial about himself and his drug use and risk his own job, he knows its a trial he can't win and so does his attorney. He's bluffing his way to the very last minute and don't you fall for it. Stay strong and only listen to one attorney now, your attorney.
