Why did the queen Elizabeth hate Lady diana ?

I don't think the Queen has hated Lady Di, her daughter-in-law at all.It was something else instead.The Queen was convinced that Lady Di was responsible for a divorce from Prince Charles.The Queen is well-known for her strong moral principles.Only recently the Queen has aproved of a marriage between her son,Prince Charles, & his longtime mistress Camilla.However,the Queen has stated she should remain a Duchess even after the coronation of Prince Charles. That means that Camilla would never become our future Queen, not only because she's an American but mainly because she is a divorceé.Prince William's wife Kate however is in Her Majesty's favour so she would become the Queen someday,although a commoner.Late Lady Di was just a substitute wife to Prince Charles for it was Camilla that he should marry, not Diana,in the first place,yet the Queen has objected their relationship for decades! Believe me,the Queen didn't hated Lady Di,it was more of a disagreement between the two on a concept of motherhood & a concept of fidelity.
