Sara is right, he (in the past) would completely throw out the idea of firing her, wouldn't even consider it. Now I think he 'gets it'. However, I think he is stuck in that phase where he thinks its ok to continue a relationship (working, friendship, whatever) with OW and you shouldn't have a problem with it. Hopefully he'll come to understand!
You are doing great, making him stay away from you, giving yourself space.
