You keep saying that "she wants this more than ever now" as if what you say has a bearing on her. Let me tell you one thing, You cannot change her, you can only change yourself.
One of two things will happen if you change into a happy, confident MAN, a better MAN than you were before. One, she will delay the divorce, or two, You will be better prepared for the divorce.
I know it is hard, but do not believe that there is no effect on her if you change for the better using the techniques that are here. This can only be done however, if you really make the changes for yourself.
Kinda weird I know, but do you get what I am saying?
