'Sister Wives': Robyn Cries Over Christine Leaving Kody (Exclusive)

In ET's exclusive look at TLC's 'Sister Wives,' Christine breaks the news to the other wives about her leaving Kody. Christine decides to film the moment on the family's phones rather than use the show's film crew, so the situation could remain private between the five of them. As she breaks the news, Robyn gets emotional and Meri is in shock, but Janelle claims says she saw it coming. 'Sister Wives' airs Sundays on TLC.
