Alongside a loving black-and-white photo of the two laughing and kissing, posted Thursday, August 5, the actress shared that she and her hubby decided to split. While addressing the heartbreaking news, Bosworth gushed over the love the former flames got to experience.
"The beginning is often the best part of love. Fireworks, magnets, rebellion — the attraction. The onset signals a wide open expanse of possibility," the 38-year-old began, as she reminisced over the best parts of falling in love. "Split a burger with someone when you are falling in love, and you can die happily knowing this is your last meal."
"Buy a bottle of whiskey and share shots, pour me a waterfall. Play that perfect song on the jukebox and dance with someone you have known your whole life, though you met minutes ago," she continued.
The brunette beauty noted: "Inherently we fear an ending," as it's hard to come to terms with losing "what you have because you got what you wanted."
"To be attached to the expectation of the outcome. The great Unknown," Bosworth added. "What if we chose not to fear but instead, to love. If that most delicate and vulnerable last flicker to the flame became another type of furnace entirely." Despite ending the intoxicating love they had, the Blue Crash star acknowledged: "Perhaps this will sound strange to some, romantic to others. To us: this is truth."
Bosworth said her and the 50-year-old's "hearts are full, as we have never been so enamored and deeply grateful for one another as we do in this decision to separate," emphasizing that they "have chosen love, every time" throughout their lengthy time together as a couple.
The Straw Dogs actress candidly shared that the two "hold hands as tightly today as we entangled fingers on our wedding day," and their "eyes look more deeply into one another, with more courage now."
Their time together as a couple may be coming to an end, but the actress insisted their love will never diminish. "In the process of letting go, we have come to acknowledge that our love will never end," she touchingly wrote. "The connection does not simply disappear. The love deepens, the heart expands."
While knowing their breakup will be anything but easy, she added: "We know the 4 am calls are coming. Songs will be exchanged to communicate only what songs can do. We laugh as we plan for our next movie together and are excited to share our latest collaboration."
"We believe the most epic love stories are those which transcend expectation," Bosworth noted before praising the love they had. "Our greatest honor has been to experience love like this, and to continue to marvel at the beauty of love's evolution."
Bosworth and Polish's chapter may be over, but she said the next is about to begin. "What happens when we reach the end of something and realize … we are just at the beginning."
The newly single star concluded: "This is love. And we will drink that down," before signing the post with the couple's first names.
The former couple first met when Polish directed her in the 2011 drama Big Slur, and it was love at first sight. Bosworth and Polish went on to tie the knot in August 2013 at The Ranch at Rock Creek in Philipsburg, Mont.
The Superman Returns star previously opened up about their relationship before they wed, telling InStyle UK: "I never even dated my husband-to-be." She explained the filmmaker told her "after just a few weeks, before we were even together, 'I'm going to marry you.' He just knew."
