Are you reading her text messages? You need to stop snooping. Would your W want to be with someone who is snooping and reading her private messages?
You need to focus on Sandi's rules and DBing techniques. You change up so many methods in the course of a day, how do you know what works? You need to commit to something for more than an hour or two.
You need to show your W changes through actions, not words. You have received the same advice from multiple posters and all you are giving us is lip service. If we can see you haven't changed, so can your wife.
Its the actions not the words that will make the difference.
