Save me from myself, need true guidance.

Hats off to you, you're owning up to your mistakes.
I have actually made a few very similar ones myself. And like yourself, would do absolutely anything to show that those mistakes would never happen again.

Somwtimes, our wives are just done. You may have to prepare yourself for that possibility.

Be VERY careful on the validating there. Make sure you only validate what is valid. When our wives feel like they're done, they will throw some crap in there too (blatant history revisions, and some outright lies)
Don't dismiss those, question them! It's important to make her feel understood. Important that you actually understand too.
