Kyle Richards got emotional when thinking about the possibility of ending her marriage to Mauricio Umansky on The Real Housewives of Beverly Hills. "There are times in life that you're wondering when should I pull the plug on this marriage," Kyle, 57, said during the Bravo show's season 15 finale on Thursday, April 16, "I feel like, you'll know when that time comes. I think there'll be a moment where you say, 'Ah ha, OK, this is that moment.'" She continued, "I know that that's going to happen for me, probably soon. So, when that moment comes, I will know and I will act on it.
