Blondie's posting of that old '77 WT answers this whole question. All she has to do is write a letter to the elders saying she has sufficient reason to believe the marriage is scripturally ended (she's met his girl friend, after all, and it appears to be common knowledge in the family that he's had several 'relationships'). The elders, believe me, will be all to happy to put this behind them.
