It sounds like he's satisfied with what he has already accomplished. I'm even more pessimistic now that we'll ever see any improvement in his game.
As for his becoming a father, he might do fine. Usually young people don't have tens of millions of dollars in the bank to help them along, but he does, so good for him. And he's obviously not obsessed with his career, so maybe that means he's more emotionally prepared to carve out a big chunk of his life for something else. He seems like a nice enough guy and, if his play on the court is any indication, not overly aggressive. Maybe he'll play only a few more years and then decide he's found something more fulfilling to do.
