OTMT, don't despair! You wife admits to loving you and is willing to work toward change. Something many people on this site would give an arm and a leg for.
Your above post about desiring to walk away reminded me of a book I really want to read in the future.

Why Women Talk and Men Walk: How to Improve Your Relationship without Discussing it by Steven Stosny

I really like this author and an eager to read it.

Anyhow, I will say it again- if you make changes in how you act and react to her then she will unknowingly also change.

It really does work that way.

Anyhow, happy V-day
