Bobbi,
I know you have kindness in your heart and can probably only think the best of others. But please look at this situation from the JW organization's standpoint. According to "esw" (the one who started this thread), his sister and her husband are "basically fanatical" JWs.
I highly doubt that her not answering his emails was because "she had to struggle" to make the break from him. She was simply doing what the organization demands of her. The rule of the organization is that communication with disfellowshiped and disassociated persons must come to a complete stop, except possibly for necessary family business. That basically means "cease and desist, or else you will get disfellowshiped too!" That is a rule that has been in place for decades. Most JWs do not struggle in their minds and hearts with this requirement. In their hearts, they feel the organization's rule is the only way to teach the departing person a lesson. And they demonstrate much more concern for obedience to the organization than they show a desire to keep up family relationships.
She finally wrote, but not to express appreciation for his concern and interest in the family. Instead, she wrote as coldly as she could, as I see it:"DO NOT CONTINUE SENDING EMAILS TO ME OR ATTEMPT TO CONTACT ME OR MY FAMILY."
Where is the evidence of "struggle" and "hurt" or even that there might be a 'change of mind' someday?
