Kate Middleton and Prince William’s relationship hit a bump, leading to a brief breakup, but they found their way back to one another.

In the new book William and Catherine, The Monarchy’s New Era: The Inside Story, out March 10, author Russell Myers follows the Prince and Princess of Wales’ love story, from the start of their romance as college classmates to a modern royal marriage.

However, the couple had a brief split in 2007 after Kate pushed for commitment but William felt they were on “different pages.”

In PEOPLE’s exclusive excerpt below, Myers shares how the pair came back together.

Their reunion a few months after the split began quietly.

William decided to make his move. At first, he texted and asked to speak, wondering if Catherine would even reply. With Catherine unsure of William’s motives and unwilling to let her guard down just yet, the initial exchanges were tentative, if a little frosty. William explained that he was missing her and floated the idea of them still attending a party that had been in their [calendar] for months. Reluctant to commit over the phone, Catherine said she would consider the proposal, although she did agree they should talk, if only to clear the air.

Fellow guests said as soon as William and Catherine set eyes on one another it was clear their love had not extinguished. The couple peeled off from the rest of the party and spent hours locked in deep conversation. Catherine listened intently as William attempted to break the deadlock, laying out his reasons for doubting what they had. He talked of his fear of letting someone truly experience the world in which he lived, and also his fear of rejection if he did let himself get too close. Catherine, of course, knew that she still loved William deeply. That was why she had been so explicit in her demands. She was willing to agree to a future, if only he would stop allowing outside factors to affect his judgment. After speaking for what seemed like hours, William’s charm, it seemed, had worked. The couple returned to the party. As the cocktails flowed and the dance floor filled, they only had eyes for each other.

Nearly 15 years after they walked down the aisle at Westminster Abbey, the pair are parents of three — Prince George, 12, Princess Charlotte, 10, and Prince Louis, 7 — and a pillar of the modern monarchy.

“Family is everything to them,” the author tells PEOPLE. “They believe that having a strong, stable environment at home gives them the best chance of succeeding in what can be an incredibly challenging institution.”
