Even the man who knows how to tug at women's heartstrings with his epic tales of love couldn't save his own relationship!

Nicolas Sparks, the author of The Notebook, has confirmed that he and his wife, Cathy, are calling it quits after 25 years of marriage. "Cathy and I have separated," the 49-year-old writer told 'People' of the breakup.

"This is, of course, not a decision we've made lightly. 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."

The couple married in 1989 and are parents to five children: sons Miles, Ryan, and Landon and twin daughters, Lexie and Savannah.
