It happened to me, too. I ended up just separating my pair of Reeves. I know that tortoises that have lived together all their lives will miss a buddy or mate that dies. They don't understand death, though. It is natural for male turtles to chase away other males and to chase females.
Injuries do happen but they are rare.
You could try housing them together again later in the year, when breeding season is over, and they might do fine. Or they might not. But, your turtles will not suffer unduly from this separation. The male might be disappointed, and the female most certainly will be relieved.
