It's doubtful that he'll be using this as inspiration for his next book.
Sparks confirmed the news himself. "Cathy and I have separated," he said.
"This is of course not a decision we've made lightly," he continued. "We remain close friends with deep respect for each other and love for our children. For our children's sake, we regard this as a private matter."
Sparks met Cathy during his senior year at Notre Dame and the couple wed in 1989. They are parents to five children--Miles, Ryan, Landon, Lexie and Savannah.
Sparks has gone on to write 17 novels, many of which have been turned into successful feature films, including The Notebook, A Walk to Remember, The Last Song, Nights in Rodanthe and the soon-to-be-released The Longest Ride, starring Britt Robertson.
