Good, you've made a decision. Go with it. Just remember... this is a long haul. It took a long time for your wife to feel the way she does. It will take her a long time to think otherwise again.
Work on you, make those changes permanent. It's been 7 months since my BD with precious little progress... mostly down to my weakness in applying the rules and techniques. Some posters have been at it for years. Be very patient.
