Advice needed desperately

Over a year ago I found out that my husband of 6 years has issues with pornography and infidelity. Of the 3 cheating instances, one was with a woman he hired for a “sensual massage”. The others were with men with my husband acting as the “bottom”. I also found that he had contacted others to visit him while he was out of town at hunting camp. I don’t believe any of those were carried out due to one reason or another. I “hacked” into his Craigslist account and other private accounts he had set up. We have gone through counseling until I was released by my counselor and he moved to just going to Sex Anonymous meetings. He was going to to five or more a week and then eventually cut back to one per week, which he now doesn’t go to at all. Last night he told me that he had been seriously think about divorce for the last month. He said he was going to wait until after Xmas to tell me, but when I point blank asked him he told me. I truly and deeply love this man and want to work things out. I quit my job of 18 years to work with him and support his company. We worked together for 3 years and it was wonderful. Another job opportunity in The field making a good salary came up and I took it and worked there for a year. I then quit with his full support to begin working a small farm to basically practice for when we reached our dream/goal of owning land and living as self supported and sustainable manner. Growing our own food and livestock. I also took out a 40K advance on my retirement funds to help speed up the process. And now he’s seriously is considering ending our marriage. Any advice as to how to fix our issues would be appreciated.
