Dwyane said that people immediately made assumptions about what 50/50 means, but for him and Gabrielle it means something a little different.

“I have 20 to 50 responsibilities and my wife has 20 to 50 responsibilities, and when I say that, that means she has her mother, she has her sisters, she has her dad, so she has a lot of things she’s responsible for,” Dwyane added. “She pays 100 percent of that and you know what I do? I pay 100 percent of my life.”
