I believe others have noted examples of elders supporting separation and/or divorce on the board.
My own personal experience with a couple in this situation was the husband was given very strict rules about what he could and could not talk about with his DFed wife. He was told it would be preferable if he would sleep in a different room and have very little to do with her until she was reinstated.
There was never any doubt that his wife was repentent (she was only DFed because she needed to be taught a lesson). There was never any doubt she would be reinstated after 6 months (she was told she would be). In the meantime, the elders found it necessary to be invasive in their marriage relationship.
