For the many of us who has never been on the other side as the "boss"/supervisor and decide to fight fire with fire, let me give you an analogy. Think of the experience where your boy-friend/gal-friend for many years/months decide to end it suddenly. The hurt can sting you and lead into irrational behavious (hence the boss reaction). Feelings of betrayal etc are common. Look on the bright side, he really treasured you. I would suggest to request - the HR manager (if there is one) - a Senior colleague that can stand up to the boss to mediate. Do not burn bridges. This advise has served me well for the more than 10 years since I've worked.
