"You will get through this, his loss and his mistake," one commenter wrote. "So very sorry you are going through this during the holidays."

The This Is Us star filed for divorce from his wife of two years in late November. The couple had been spotted at a Golden Globe party together just days before and showed no signs of a split.
A source previously told ET, "People close to Justin and Chrishell are completely shocked by Justin filing for divorce. The couple has always been incredible with no signs of things being on the rocks. Friends are speculating this was an impulse on Justin’s side due to something that happened, and are hopeful the couple can work things out."
However, according to documents obtained by ET, Justin listed the date of separation as July 8, 2019. Justin has not publicly commented on the divorce filing, but he was spotted out without his wedding ring just one day after filing.
