In ET's exclusive look at the finale for TLC's 'Sister Wives: One on One' special, Christine Brown reveals to host Sukanya Krishnan the moment she knew her marriage changed for the worse. Christine says when she began standing up for herself and saying ‘no’ to things, her husband, Kody Brown, didn't like that. Kody disagrees with Christine’s claim and asks Sukanya to stop talking about their prior relationship, which ended in September when they announced their split on Instagram.
