You ask why on earth would you continue to work with your soon to be ex-partner everyday. Well, I can not give you a universal answer to that question. But I can tell you that if it were me and my wife fired me because I wanted a divorce, I would certainly not be willing to finalize things amicably anymore. Probably the complete opposite. I'd be foaming at the mouth with a new purpose in life - to annihilate her in court.
