Petraeus’ friend, Brig. Gen. James Shelton, is saying that Broadwell is responsible for the affair with the married retired general.
Petraeus “was the innocent one when it came to relationships,” Shelton told the Daily Mail of London’s website MailOnline. Besides being beautiful, intelligent, and a fellow West Point Academy graduate, Broadwell is “a savvy woman,” Shelton said. “She’s not a kid. In a lot of ways I think she knows more about the world than Dave — I’m talking about sex.”
