Jana Krameris looking ahead and celebrating life as a newly single woman.
Sharing aphotographof herself throwing her hands up in the air while on a boat in a tropical locale, Kramer began the caption of her post, writing, “Free. And not looking back.”
“I thought not celebrating 6 years today would feel heavy and sad…. and though there is sadness in the broken, there is more joy, happiness, freedom and self love than I’ve ever experienced,” she continued. “The weight has been lifted and I welcome the unknown, because there is so much beauty in what’s next.”
Kramer added: “Find your strength and set yourself free…”
On April 21, Kramer announced in anemotional Instagram postthat she and Caussin, 34, were separating.
“‘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,” the mom of two wrote. “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.”
“Please know that I still believe wholeheartedly in marriage, love, and rebuilding. I just can’t fight any longer. It’s time to heal,” Kramer 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. 💔.”
