What We Know About Jana Kramer And Mike Caussin's Split

Another Hollywood couple bites the dust. Country singer and former "One Tree Hill" star, Jana Kramer, took to social media to reveal that she and her husband of nearly six years, former NFL star Mike Caussin, have called it quits, and Us Weekly confirms that Kramer has already filed for divorce.

"'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. I've fought y'all. I've loved hard. I've forgiven. I've put the work in. I've given everything I have, and now I have nothing else to give," the actress, who shares two kids with Caussin, penned in an emotional statement on Instagram on April 21.

"Please know that I still believe wholeheartedly in marriage, love, and rebuilding. I just can't fight any longer. It's time to heal," she continued. "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. I'll always encourage you to continue the good fight, but you can't fight it alone."

Kramer has been open about Caussin's infidelity in the past

The couple previously separated in 2016 after Caussin entered rehab for a sex addiction after cheating on Kramer with "several different women" (via Us Weekly). In 2017, the couple reconciled, and since then Jana has been open about her husband's past behavior and has detailed their relationship ups and downs on her and Caussin's podcast, "Whine Down." Kramer and Caussin even co-wrote a book about relationships together, titled "The Good Fight: Wanting to Leave, Choosing to Stay, and the Powerful Practice for Loving Faithfully," which was released in September of last year (via Amazon).

However, a source close to Kramer revealed that when it comes to Caussin, old habits die hard, and he was reportedly cheating on Kramer in the months leading up to their divorce." Jana realized Mike's repeated behaviors were not going to change and it was time to let go," a source dished to Entertainment Tonight.

Another source told People, "He cheated and broke her trust again. After fighting for the marriage for so long, she's come to terms with the realization that his patterns were never going to change." The source also said that although the split is tough on her, Kramer's "focus now is on their kids," five-year-old Jolie and two-year-old Jace.

Friends, fans, and fellow celebs showed their support for Kramer after she shared the heartbreaking news on Instagarm

Jana's heart-wrenching Instagram post garnered over 150,000 likes as of Thursday afternoon, and people from all over flocked to her Instagram post to show their support for the mom of two. "Aw babe. I'm sending you all the love and healing vibes. I'm so proud of you. Keep that gratitude journal close by," former "Vanderpump Rules" star Billie Lee wrote. While other reality stars, like "Real Housewives of Beverly Hills" star Teddi Mellencamp, told Kramer that she was "sending love her way."

While many fans and fellow celebs showed their support for the Lifetime movie actress, others were outraged about the news. "This woman's husband cheated. They got back together. They wrote a book about how to get past cheating, and then he cheated again. Men are so embarrassing," one Twitter user wrote. To which another replied, "I just want men to be honest about their ability and or willingness to be monogamous. It's the deceit for me. Just say you can't/don't wanna do it!"
