I knew of a situation like this. The man who was divorced by his JW wife because she could not stand him. He remained active in the JW's, she did not. But for years the did nothing. Then one day this brother went off and married another JW woman, though he was not spiritually free to do so. He and her were publically reproved but neither were disfellowshipped. They repented for breaking the WTS law, and basically got a slap on the hand.
The Elders were sympathatic to his plight, and felt helpless to help him. His ex-wife never got involved with another man ever again.
I talked to her here about 5 months ago, she has no use for the witnesses, and had wondered how her ex had pulled off getting married again without being disfellowshipped. Sympathy of the elders basically is what saved them.
Now if he had not been a faithful man, even once an elder, and continued straight though serving the congregation and had not married a JW gal it would not have gone so well with him I am sure. His activity is what saved him from disfellowshipping.
