Spouses - Confessions

My husband and I have been married for over 29 years. Ten years ago, I discovered that he was having an emotional affair with a woman in another state that he knew from his teenage years. They had been communicating quite frequently by their cell phones and it had reached a point where he was questioning rather he was “in love” with me or not. During the restoration time, he also admitted to a one-night stand he had with his secretary 8 years before, about a year after the birth of our 3rd child. We sought counseling, did the hard work, and both felt that our marriage was restored and actually renewed our vows for our 20th anniversary. Since then our marriage has had its normal, ebbs and flows, but for the most part has been good. Earlier this year, I discovered that he was having an on-going Facebook conversation with another woman. The conversation was VERY inappropriate and had several sexual inuendos and flirtatious comments. I confronted him and at that time he asked that I know all of his passwords to email and FB so that he cannot have any secret areas in his life. Over the next few months he genuinely seemed to be trying and God was working on him. Two months ago, he voluntarily confessed to a sexual affair that lasted about 2 months. It occurred prior to the emotional affair, 10 years ago, he didn’t confess it during that time because he felt that would have been the “straw that broke the camel’s back”. He had lived with this secret sin for 10 years and felt that in order for us to have full restoration that it had to be disclosed as well. A week after this confession, I discovered porn on his laptop. He confessed that he had started looking at it when he was issued a new work computer and the old one was no longer being monitored by the company server. So this had been going on for about 8 months, it was not a daily thing, he visited sites once or twice a week, he was very ashamed of this and I believe him that he truly does not want this to be a part of his life. About a week ago, while having his quiet time, God reminded him of something else he had done that he had forgotten. Earlier this year, he went on a video chat site and chatted briefly with a woman from another country, during that video chat session, they both removed clothing and masturbated while watching the other. When he remembered this, he really became ashamed of what he had done, he voluntarily confessed this to me, as well. The next day or so he started worrying about rather that episode was possibly captured and feared it showing up somewhere on the internet. He went back to that video chat site to see if there was a way to trace it, while looking for it, he fell to the temptation of viewing porn sites again. He had promised me, that he would tell me if he ever fell to that temptation again, but he did not disclose this to me, I found it myself. We have purchased X3pure for men because he really does not want to have this sexual addiction. I want to believe him. In every other area of his life, he is a very moral man, a Godly man, teaches Bible study, is a good husband and father. I want to believe that he can change and be the complete Godly man that he and I desire for him to be. Am I being naïve to continue to stay with him? What help is there for me? I don’t want to be an enabler I want to do what God desires for me to do, but I am not confidant in myself to discern that will for my life at this time.
