I've known lots of people who have navigated relationships where one person cheats. There is light at the other side of the tunnel. We rarely hear of the relationships where people fought hard to keep it together, despite the challenges that arose. It's only the break-ups we hear of, which sometimes involve cheating. If he doesn't tell his wife and she eventually finds out, the consequences are going to be different than if he comes clean, acknowledges he has a problem and wants to work with her to move on from it. His mistakes, as I pointed out, was coming here asking for advice. Many people's previous relationships here were not good, and so do not represent a good sample size to be asking for advice from. It's clear that he hasn't been able to kick the habit alone. He needs someone to keep in accountable, and his family is a potential avenue for doing so as they are already invested. The biggest fear he will have to get over is the million potential ways his wife could respond to being honest. If he wants to go to the sex addiction equivalent of AA, than so be, but based on his post, that doesn't sound like something that will work.
