Billy, you've likely heard this a lot and will continue to hear this around here: Only time will heal wounds. While this is going on, YOU have to be continuously and actively working on YOURSELF. You made the decision to change after your wife walked out the first time, so the idea is to keep it going, okay?
Keep improving, keep it real, keep praying (if you're religious; I am) and keep on truckin'.
Welcome to the site, BTW. There are a lot of great people here with different backgrounds and experiences, and who are at different parts of the "process", so you won't be in short supply of support or resources.
