As Liam Hemsworth filed for divorce from Miley Cyrus on Wednesday, details about why the actor wanted to divorce the singer have been revealed. While court documents indicate that Hemsworth filed for divorce because of “irreconcilable differences” the split between the couple was a long time coming.

According to a source for Radar Online, Hemsworth, 29, initiated the split from Cyrus, 26, claiming that the couple was on a break to sort out their marriage problems, which he had hoped would stay private between the two.

Hemsworth wanted “to take a break and see if anything could change,” the source for the news outlet said. “Liam wanted to leave, but he was hanging on by a thread hoping Miley would understand where he was coming from.”

The couple had been on a break for months, which was abruptly interrupted by Cyrus’ very public hook up with Kaitlynn Carter, 30, in Italy, where the women were vacationing.

Hemsworth was reportedly blindsided by the make-out session between his wife and Brody Jenner’s ex, which drove his final decision to file for divorce.

“So, for Liam, that was the final nail in the coffin,” said the source. “He wants to put all of this behind him, move on, and find a fresh start.”

Hemsworth filed for divorce from Cyrus on Aug. 21. The couple reportedly has a prenuptial agreement, where Hemsworth is not seeking spousal support, according to E! News. Both stars have homes they purchased before their marriage, and the prenup indicates how the assets would be split between the ex-couple expect for all the animals they jointly parent, according to the news outlet.

"Liam is just done with it. There is no turning back and he knows he wants to move on," a source told E! News. "They have not had a lot of communication. There is nothing to say."

Cyrus and Hemsworth were married less than a year.
