Up until that point, there were no public records or credible sources stating that Prince Charles said five specific words that caused the breakdown of his marriage to Princess Diana.
Prince Charles and Princess Diana's marriage faced various challenges, including differences in personalities, interests, and a lack of emotional intimacy. Their relationship was complicated and affected by several factors, both personal and public, which led to their separation and eventual divorce in 1996.
It's important to avoid relying on unverified rumors or sensationalized stories about such sensitive matters. The breakdown of any marriage is typically the result of a combination of factors and not solely due to a single statement or incident.
