Prince William Marriage: New Biography Claims Prince Doubted Marriage To Kate Middleton

A new biography of Prince William claims that the future king was so scarred by his parent's failed marriage that he doubted whether he could be faithful to one woman.

According to royal biographer Penny Junor, the author of "Prince William: The Man Who Will Be King" (which hits bookshelves June 4), Prince Charles and Princess Diana's highly publicized affairs contributed to Prince William's delayed marriage proposal to now-wife Kate Middleton.

“The problem was William: he had very real worries about whether it was possible to love just one woman. After his hurricane childhood, he was understandably cautious about committing to a relationship," Junor writes in the book, which was excerpted by The Daily Beast.

Assuming Junor's allegations are true, were William's fears justified? A 2005 study by researchers at the University of Utah indicated that a couple is twice as likely to divorce if one spouse is from a divorced family, as is the case for Will and Kate.

Still, as HuffPost blogger Judith Wallerstein wrote in November 2010, no one can predict the impact of the divorce on Prince William's marriage. "On one hand," the psychologist wrote, William's "history may make him more aware of the fragility of marriage and the importance of trust, fidelity and honesty in his relationship." Conversely, the future king "may identify with the long line of broken relationships in his family and mistakenly conclude that he has little control over what will happen."

So will his marriage last? Only time will tell.
