"It's hard work," the father of four continued. "Jo and I have struggles and fighting and arguments just like anybody else. This isn't like we got lucky and hit the lottery and the two perfect people fell in love."

"There are so many places where she's refined me as a man, as a husband," Chip added. "I'm a better person because of the experiences we've had together."
