Kate Bosworth separates from husband Michael Polish after almost 8 years of marriage

Kate Bosworth and husband Michael Polish are parting ways in their marriage.

The "Blue Crush" actress posted a black-and-white photo of her and Polish kissing, accompanied by a lengthy Instagram caption starting with lines from the movie "Big Sur," during which they first met on set. Bosworth continued in the caption expressing the love the two shared and will continue to share –apart.

"Our hearts are full, as we have never been so enamored and deeply grateful for one another as we do in this decision to separate," Bosworth wrote in her Thursday post. "The connection does not simply disappear. The love deepens, the heart expands."

Bosworth and Polish tied the knot in 2013 after Polish popped the question during a trip to South Korea. Their wedding took place on a Montana mountaintop with a small group of close friends and family.

Aside from collaborating on "Big Sur" and the 2017 movie "Nona" the actress-director duo also put their heads together to launch a two-week film school in Montana through the Montana Institute for the Arts to create a "hands-on approach to the moviemaking process."

Though Bosworth announced the two would be parting ways, she also said their collaborative connection would continue.

"Our greatest honor has been to experience love like this, and to continue to marvel at the beauty of love’s evolution," she added. "What happens when we reach the end of something and realize … we are just at the beginning."

The couple first met in 2011 on the set of "Big Sur," but Bosworth told Marie Claire in a 2015 interview that they didn't act on their attraction while filming.

"There are so many people that hook up on movies, and you wonder if that’s real, so we didn’t go there," Bosworth said. "We could wait to see what would happen."

She added: "They always say, ‘you know when you know’, and I had found that quite frustrating my whole life. I thought, yeah, but how do you really know? But it’s true, he walked in and it hit me like nothing I’d ever felt before."
