Shannen Doherty shared an emotional tribute on Monday dedicated to her husband of five years, Kurt Iswarienko, on Instagram.
The Heathers actress posted a photo of the pair on their wedding day, holding hands and smiling.
“Our wedding was exceptional and not for the big event it was. It was exceptional because we committed for better or worse, in sickness or in health to love and cherish one another,” she shared. “Those vows have never meant more than they do now. Kurt has stood by my side thru sickness and makes me feel more loved now than ever. I would walk any path with this man. Take any bullet for him and slay every dragon to protect him. He is my soul mate. My other half. I am blessed.”
Doherty told PEOPLE she was diagnosed with breast cancer in August 2015.
In early September, she told ET her marriage was “always fantastic” but “it’s even better now.”

The Charmed actress posted the photo in response to an Instagram challenge by one of her good friends, Sarah Michelle Gellar.
Gellar has also posted a photo for the “Love Your Spouse Challenge”, sharing a photo of the first holiday she spent with her husband, Freddie Prinze Jr.
The challenge, she wrote on Instagram, was meant to “spread love (and the joys of marriage) by posting seven days worth of happy pictures.”
