We entered the lives of Lisa Wu and Ed Hartwell on “The Real Housewives of Atlanta,” and even though the couple had children from preceding relationships, it was apparent that this family never saw it as a difficult adjustment. Ed told ESSENCE.com about his bond with Lisa’s children. “Me and my sons have a great relationship,” he said. “I tell everyone I have three sons. They call me dad. I never say my stepkids; they are my sons.” Ed also has a teenage son from a previous relationship.
