Zac Affleck posted an emotional apology on social media acknowledging he damaged his marriage to Jen Affleck, a cast member of 'The Secret Lives of Mormon Wives.' "I messed up. I wasn't the husband I promised to be," Zac wrote, according to Yahoo Entertainment.

The apology comes amid public speculation about the couple's relationship following Jen's candid discussions on the Hulu reality series about their marriage struggles and religious differences. Jen has been open about navigating faith transitions while Zac has remained more traditionally observant.

Five of the show's eight original cast members have now filed for divorce since the series premiered.
