I actually think this is good news. You have reach “critical mass.” So now he is faced with a two choice dilemma. My only advice to you is to not react too quickly if he does not respond like you want. You may not have “cooked” him enough for him to see past his blinders. Too quick of a decision at this point may create irreversible damage. It will be very difficult for him to wrestle with his anger and come to the right choice, so try to really put on the compassionate, caring wife façade and show him to the best of your abilities everything he has asked of you.
Critical mass means dropping all denials, facing the truth and accepting responsibility. It does not mean that you win or he wins. It means that all the posturing is placed aside and the real understanding, negotiating and compromising can take place. So keep an open mind, take time to think over your decisions before saying anything, hold onto yourself to not react first, no matter how he may try to pull you into it. That will give the coming situation the best environment to develop in a positive way.
