I always wondered "what happens if he refused?" If he says no, shouldn't he be equally obligated to break up with her for making the suggestion? At that point the "it was just a test!"retort would just seem like backpedaling.
It's no wonder that the happiest marriages I've seen in this cult were between "spiritually weak" couples. The more you follow the rules, the worse job you'll do finding a compatible spouse and the worse you'll be at putting them first before anything else.
