Wow, I think this almost sounds like the end stages of MLC to me. It's almost like everything is crashing down on your husband, stress over job, trying to keep two women from becoming angry, etc...
I can't blame your anger. But do try and calm down prior to saying or doing anything. I seem to always regret what I do in anger. If you still feel the same after the anger has passed and you've had time to think... then you know you will be going in the direction that truly feels right for you.
There is no arriving, ever. It is all a continual becoming.
