I consider his situation a win win, rid of a cold wife and out of the cult.
If he wanted to stay he should have cheated for the legitimate divorce then repented after marying the new woman.
His wife was the one that wasn't giving her husband his due, no elder in the world would hold that against another man.
Although I knew a sister who's husband cheated on her and ended up getting remarried. She protested his being reinstated because she forgave him and that meant he was still scripturally married to her.
Not sure how that one ended up working out, he never came back to her but I don't know if he got reinstated or not.
