Patricia Arquette and Thomas Jane are breaking up – again.
Despite working through a separation last year, the Medium actress and Hung actor have decided to get a divorce, his rep tells PEOPLE.
“The split is completely amicable and their prime focus is their daughter,” says the rep. “They ask that their privacy be respected at this time.”
The actress first filed for divorce from Jane in January 2009, but the two reconciled later that year.
