Imagine your father had married your innocent teenaged mother for convenience, while continuing his affair with another woman throughout the marriage.
Imagine he was head of the Church of England, but stood at the church altar lying when he vowed be faithful to his bride.
Imagine he drove her mad with his infidelity and coldness.
Imagine all of this went on in the public eye and the whole world saw her humiliation.
Imagine she died, your father married his mistress and you are supposed to pretend you respect them, and revere the pair of them as the king and queen.
How the hell would you feel?
