1) DO NOT talk to your wife about this. Not one flippin' word. Do not confirm, deny anything! It would be like pointing a loaded gun at your head. If she brings it up, hold up your hand and leave the room.
2) Talk to a lawyer about he ramifications here. (What you can/can't say; what you can/can't prove) Do not tell your wife ANYTHING about talking to a lawyer. You need to be the best armed man in the room.
3) With your attorney prepare a BRIEF written statement. Tell the board that you will be happy to answer any and all of their questions after a brief statement that should answer most if not all of their questions. That gets what YOU want to say into the record.
