Royal houses weren't about love in the past and often both men and women had affairs while married. It was not uncommon for illegitimate children to be born, who then received an education and were brought up at court.

Although the royals have some special rights and privileges, they can not go ahead and stray outside their marriages. Royal family members have a moral responsibility and should be role models for their people.
