Will Smith may be an A-list actor, but when it comes to his marriage, he says he used to be such a bad husband to Jada Pinkett Smith that he deserved an "F." "There was a period of time when mommy woke up and cried for 45 days straight," Smith revealed Monday in a preview clip from the next episode of Jada's Facebook Watch talk show, Red Table Talk. "That was the worst I've felt in our marriage. I was failing miserably." Smith made his comments in front of daughter Willow Smith and Jada's mother Adrienne Banfield-Jones, who were also guests on the show. The episode premieres on October 22.
