How to treat a non-Baha’i spouse

As to thy respected husband: it is incumbent upon thee to treat him with great kindness, to consider his wishes and be conciliatory with him at all times, till he seeth that because thou hast directed thyself toward the Kingdom of God, thy tenderness for him and thy love for God have but increased, as well as thy concern for his wishes under all conditions.
