Why Didn’t Prince Charles Marry Camilla in the First Place?

After years of affair rumors, Charles admitted to starting his romantic relationship with Camilla in 1986. Nonetheless, he and Diana didn’t divorce until 1996, a decade after the affair began. Camilla and Andrew divorced in 1995, and she started seeing Charles again privately. When Diana died from a car crash in 1997, they kept the relationship even hush-hush out of respect for her.
