Q&A Should I Suggest Addiction Counseling to My Mate?

My husband's acting out meets the definition of sexual addiction. Since my first D-Day several years ago, when he said that he had been involved in online only pornography and relationships for a couple years, he has changed and matured in amazing ways. Earlier this year he voluntarily confessed that his pornography use began as a teen and that he had multiple hook-ups before our marriage and anonymous sex once after we were married. Though he has done some individual and couples counseling, and currently seems to be doing everything he can to invest in our marriage, I'm wondering if I should suggest or even push for him to do addiction counseling or something like that.
