Based on recent posts, sounds to me like the DB approach has been working. Your WW has been noticing the new, improved HurtJef. I know it's hard, but try to avoid the backslides. Don't give her excuses to justify why she left. I don't think you've made any mistakes that can't be corrected, but stick to the DB plan from now on. If you get to a point where WW reaches out, and wants to work on things, then you will have to make a decision. I wouldn't rush it right now. Keep working on you, and let the rest unfold as it will.
