I am not good at predicting the future, so I maybe I am off-base. But I am thinking that now that his dissatisfaction is out, what will happen is that he will take his unhappiness and spread it around. You will be unhappy, and the kids will be unhappy. It seems to me that you need to make a bargain. Until he is ready to do something different, i.e. move out, he needs to not share his unhappiness with the rest of the family. He needs to act as if he is happy, and live as a husband and father. Just because he has shared with you his inner misgivings, is not a justification for dating other women while married, or having temper tantrums around the house.
