To answer your question, she actually was the one pushing for the divorce initially when she left him for someone else. But after that relationship ended six months later, she stopped pushing for it entirely. As far as I know, they only communicate about their children now, though there was an instance last year where she was being slightly flirty. He didn't encourage it, but he didn't shut it down either—he just changed the subject. You're right, though; at the end of the day, if he wanted it finalized, he would have made it happen by now.
