If he is truly addicted, he needs help and, just like for any other addict, he has to make that decision for himself. You cannot 'make' him quit. The first step, when he's ready, would be for him to be evaluated by a Certified Sex Addiction therapist. (CSAT)
If he isn't there yet, the best thing you can do is get out of the marriage. Often, such a thing is what the addict needs to smarten up. But your concern should be with yourself, not him. You probably have enabled him in some way and may benefit from a codependents group like COSA or S Anon.
