On April 23, Plum, 29, and Waller, 31, filed a joint petition for divorce in Clark County, Nevada, according to court documents obtained by PEOPLE.

Just after the filing, Plum shared a heartbreaking message on social media. “I’m devastated. I walked through fire for that man, but now I see it’s time to go,” she wrote on Instagram Stories.

God has given me an incredible life, and I’m truly so grateful for the profound love from my family and friends,” the Las Vegas Aces star continued.

“One day I’ll share my story, today is not that day. Thank you for the grace to process my pain, to forgive and move forward. Today and everyday I will continue to choose joy. Much love KP.”

Plum ended her message writing, “Philippians 1:6.” The bible verse means, “He who began a good work in you will bring it to completion at the day of Jesus Christ.”
