ForeverAlone: It sounds like she does not have any friends at all.
This is standard behavior from abusers. They will do all they can to isolate their victims, to keep them from reaching out to others and getting help. If Evans's wife had stayed in the congregation after he disassociated himself, she would have at least a few hours a week where she was not under his thumb. She could converse with others who could undermine his control, and she might just tell them things that he did not want them to know.
This bodes ill for his current situation, where she does not appear to be under his direct control anymore. So it's a question of whether her situation changes enough that she will be tempted to break away from him. I think that, in time, she will. Either through financial independence or simply having had enough of him, so that she decides she doesn't care about the consequences.
