Lone Star,

Your post seemed very sincere. If you are having any level of communication with your W have you asked her to consider joint couseling or invited her to speak with your group sponsor?

Yes, I think she can come to open her heart to you once she sees that your changes are REAL and permanent...right now she is probably afraid because no doubt you've told her many times that "it'll never happen again"...and yet it did. So her trust in your 'word' is zero...BUT that can all change with time, patience and her 'seeing' the new you under various conditions.
