My husband has been unfaithful to me multiple times during the course of our marriage as I found little pieces here in there throughout our marriage, but I got the full story (I think) this past year. Since D day we have come to the conclusion that he is a sexual addict, I had an idea to be honest but I never thought he would act out with real people. Plus I never knew there was such a thing as a sexual addiction, which we've come to learn through affair recovery. 

He seems really broken and has confessed many weaknesses, he says he desperately wants to be set free and has done counseling appointments (he found he dealt with the crisis but did not touch on reasons behind his recurring unfaithfulness, so we stopped going), has seen our pastor at church and just started hope for healing

From your point of view what else do you recommend we do to help reach a full recovery.
