Amy Krouse Rosenthal, the American author and filmmaker who created an online dating profile for her husband, has succumbed to her battle with ovarian cancer. She was 51.

The cancer-stricken writer broke the hearts of many internet users last month with her essay entitled “You May Want to Marry My Husband”.

On Monday (Tuesday in Manila), her literary agent Amy Rennet confirmed the tragic news of her passing.

“She taught us that life’s seemingly small moments are not really small at all,” Rennert told People magazine.

“Amy’s final essay, written under the most difficult of circumstances — a love letter to her husband Jason — was the ultimate gift to him and also to the rest of us. She leaves behind a legacy of love and beauty and kindness,” she said.

Before her death, Rosenthal was a successful author of over 30 children’s books, as well as journals, memoirs and picture stories.

She and her husband, Jason, had been together for three decades and had three grown-up children.

Her heartwarming piece, which detailed her fatal diagnosis and her dream for Jason to one day find love again, was published in The New York Times’ Modern Love column.  Khristian Ibarrola /ra
