Shed the fear and WAKE UP to the realization that your W has moved forward without you, so you have NOTHING to fear, NOTHING!!! Fear paralyses you, fear keeps you dying inside all the time. That is no way to live. Shed the fear, move forward...
Until you come to terms that your marriage is DEAD, I am afraid no progress can be made. No, your W won't snap out of it tomorrow, or the day after, so stop looking.
