About 10 years ago the PO of a congregation in UK left his wife, resigned from his congregation, resigned as Assembly Hall overseer and admitted he had not believed it was the ' truth ' for some years. The new woman ( not a JW ) was probably the catalyst for his action.
There must be many who just stay around rather than rock the boat and pay lip service to the org. The investment of the years requires a new investment of greater perceived value, to allow for such a life altering change ? The principle way you fall out of love with a person is when you fall inlove with someone else.
The above story is true as the guy involved was my wifes, sisters husband, I know the overwhelming sorrow and shock it caused at the time.None of his family remained in the org.
