Compatibility between two couples are almost all the reasons why they get along well, as they enjoy the same hobby, interests, and how they understand each other. Unfortunately, in the case of Princess Diana and Prince Charles, they realized that they do not share anything in common. From a simple interest in books and arts, one cannot stand the other who spends more time on his hobbies than to his wife.

Sadly, the truth was revealed after a decade and divorce, with the tragic death of the "people's princess," as their once fairy tale wedding was never really the wedding everybody wants for themselves. There were wedding jitters before that fateful day. However, they failed to recognize the common jitter for an entirely unmatched couple.

Some followers of the royal couple went on lengths to study on the astrological compatibility of Princess Diana, Prince Charles and even with the now Duchess of Cornwall. And while this is all but speculations, the personalities of each royal can attest to what extent their chemistry was to each other.

For Princess Diana who was born July 1, 1961, she was tagged as having a Cancer sign, while Prince Charles who was born November 14, 1948, was a Scorpio, with these details, there are already signs that they are compatible through their birth months. However, there is what they call too much chemistry can make or break a relationship, especially if they both know how to hurt each other.

Princess Diana and Prince Charles had an instant connection when Lady Sarah Spencer paired them, and the cameras focused on their first moment aboard the royal yacht was able to capture the strong chemistry between them. They were in love and smitten by each other, but their marriage was astrologically doomed from the start.

Because looking back on Prince Charles' unrequited love for Camilla Parker Bowles, the two royal couple have already established a quite strong astrological compatibility, which can surpass the second one with Princess Diana. The Duchess of Cornwall whose birthday falls on July 17, 1947, makes her equally in the sign of Cancer, along with Prince William and his mother, Princess Diana. That is why, although they do have similar astrological signs, what happened with Princess Diana and Prince Charles was the unfortunate downfall.

Since the marriage of Princess Diana and Prince Charles had just started, they were clearly unknown of the red flags along the way and it was already clear as early as their honeymoon. According to royal biographer Penny Junor who wrote "The Duchess: The Untold Story," Princess Diana did not enjoy her honeymoon because of Prince Charles' "wretched books."

These include his watercolors and some canvases and a pile of books by Lauren van de Post that Prince Charles thought would be a good connection between him and Princess Diana. Unfortunately, they do not share the same interests, and her sadness continues when they lived in the Balmoral. Junor wrote that Princess Diana hated the countryside, the royal family's passion for horses and dogs and even the sound of the rain pouring in Queen Elizabeth II's home.

Because of her indifference to the surroundings, Prince Charles would live their home most of the time and leave her with the royal staff to accompany her. With this situation, Princess Diana also accused of Prince Charles to have avoided intimate contact with her while they were there.

The signs started to show when Princess Diana would become too emotional and would cry a lot as she hated everything around her. According to Ingrid Seward's book "The Queen and Di: The Untold Story," Princess Diana felt outcast by her in-laws, who were the same personalities who welcomed her into the royal family. From there, the late royal felt inadequate, in addition to the lack of affection her husband was already giving her.
