It seems to be over for Jana Kramer and Mike Caussin.

The 37-year-old country singer and 34-year-old former football pro have had a storied and troubled relationship that looks to be over based on a Wednesday Instagram post from Kramer.

The "One Tree Hill" actress shared a written message on the social media app, kicking it off with the phrase, "It's time."

"As I try to make sense of a reality I never wanted to believe could be possible again, those words have now become a reality," she began. "I've fought y'all."

The star assured fans that she still believes "whole heartedly in marriage, love, and rebuilding" despite the split after six years of marriage.

"I just can't fight any longer. It's time to heal," she added. "Thank you for all the love, heart, and support, in many ways you have fought on this journey alongside me, and for that I am grateful."

The "I Got the Boy" singer concluded: "I'll always encourage you to continue the good fight, but you can't fight it alone."
