If he wanted it to be private, why in hell was he telling ESPN about his separation in the first place?
If he wanted it quiet he should have said, "That is a family matter, and like all family matters I will not discuss it with the press. I will neither confirm nor deny any questions relating to my family. So please ask me about football instead."
Pretty simple.
You don't give a reporter a "scoop" and then ask him or her to forget it. Publishers don't pay for that kind of sloppiness.
"By the way, this is all off the record, right?" doesn't cut it.
If y'all really want the rules of engagement when it comes to interviews, I'll be happy to let you know.
