TG and Gonna made some very important and valid points. IMO, you were protecting yourself for years, not protecting your wife, and you need to look into that and what that truly means. Your main goal should be figuring out why this happened and working on yourself and your issues, not convincing your wife of something.
IMO, you are quick to minimize what you've done. In your other thread, people suggested you address your porn usage in therapy and Samantha Baker mentioned a treatment program -- you did not acknowledge any of that. You remained focused on your wife and getting into MC. That suggests you think this is a marriage issue. It's not. This is your issue. The sooner you realize that, the further ahead you will be.
I'm also a BS who felt I had no idea who my husband was for the whole length of our marriage, because his own shame, he kept parts of himself hidden. His porn usage snowballed into addiction and then.....well, look where we ended up, on an infidelity site. Part of the reason for all that was his need for secrecy.
His shame, his behavior and his actions had nothing to do with me. That was a part of him long before I came on the scene. My husband would have had these issues in any relationship with any partner -- and he did. It was about him. So, does this really have anything to do with your wife's opinion on porn? Or if you look back, does this precede your relationship with your wife?
As far as your success story question -- what will success mean for you? I'd say we are well on our way because of a lot of hard work.
