Still kinda unconfirmed if you ask me, but for Neil Harman is reporting that Rafa's parents have separated:
Right now, such sensitive matters are on the mind of Nadal, at home in Majorca. For many weeks there have been whispers that all was not uncomplicated in the Nadal household, that his parents, Sebastian and Ana María, who hugged their son on the most joyous day of his life a year ago, had separated. Yesterday, we discovered that that was, in fact, the case, that Nadal had been playing in such a fog for the past couple of months, he should have been wearing luminous clothing. He is crushed and any fair-minded person has to be crushed for him.
Imagine what it has been like, trying to do your duty by yourself, your team and your profession and yet having to perform when your heart is elsewhere, the distressing nightly calls home, the wish that it were not so, the desire for a reconciliation.
Nadal never mentioned it, he played and hoped. He talked about resetting his body after having to withdraw from the championships with problem knees and yet he has a more difficult task, resetting his entire life. We wish him well.
I still hope it's not true. And to be fair, it's still unconfirmed. But yikes.
Thanks to V for posting the link.
