You have made progress, but if your wife doesn't own up her part in the beginning of it all (when you thought she was not interested in you sexually) and doesn't do her part now by initiating sex frequently enough, you would likely go back to porn eventually, because the situation for which porn was initially a solution is partially still there. Less so, but not fully out the door.

You do not meet the criteria for addiction - you appear to be high functioning, right?
