I am sorry to hear about you troubles. I would talk to a pdoc with your husband and work out a plan of action for you, something that will help you, and also will work for your husband. As far as the women go, IMO he does not have to be going out with women to deal with his problems. Without being confrontational, I think you should tell him how you feel. Start by saying "I feel that..." then "because..." and then listen to him. If he is at a loss for ideas, then suggest one or two of your own ideas to him.You may want to write down what you are going to say before talking to him.

I am no doctor or therapist. This is just what I would do in a similar situation. Only you will know what will work for you.

Good luck!
