18 hours after saying I do from her hospital bed, Heather Mosher passed away following a battle with breast cancer.
Photos of her wedding taken by her friend, Christina Karas, have taken the internet by storm, sharing a story of love and strength that has touched hearts all around the world.
Heather Mosher met David Mosher in 2015 at a swing dancing class, and after a year and a half of dating David planned to propose to Heather.
The day he intended to get down on one knee was also the day Heather was diagnosed with an aggressive form of breast cancer.
David was determined the diagnosis would not stop the proposal plan. He went ahead and asked Heather to marry him that same day, and of course Heather accepted.
"I left the plans as they were. I proposed to her," David explained to Inside Edition.
"We had the toughest year of our life. She struggled with her cancer through the traditional chemotherapy."
The cancer was more aggressive than anyone had anticipated, and doctors told David that Heather did not have long left, spurring the couple to bring forward the wedding date.
Friends and family gathered around Heather's hospital bed as the loving couple said: "I do."
The moment was captured by Heather's bridesmaid, Christina, who explained in an Instagram post that she was initially hesitant to bring out her camera.
"As someone who wanted nothing more than to see my friend truly happy, I felt I had to capture these images, which by this point I knew were her final moments with us," she explained.
"What you clearly see here is two people who were destined to be joined as one. A love like no other captured for all to see. My gift to her."
"I am in awe of the strength Dave's love inspired in Heather, even in her last hours. She was his great love and he was hers," Christina finishes.
Our thoughts are with Dave, Christina and Heather's friends and family at this tragic time.
