Sarah Ferguson and Prince Andrew’s marriage only lasted for a few years, and the reason why their relationship failed may have just been revealed.

According to the former couple’s star sign, they are not very compatible. The Duchess of York, who is a Libra has a selfish and manipulative side. Prince Andrew, on the other hand, is a Pisces and he is devoted for as long as there is strong excitement over the emotions that he feels.

On the website Astrology Zodiac Signs, it was also revealed that the former royal couple only has a 29 percent success rate in having a long-lasting relationship.

“They will both value love and this is something that will connect them over everything else. With Venus at focus, they will both need to be loved and cherish those who know how to show it and how to enjoy life,” the website stated.

On the other hand, a marriage or a relationship between a Libra and Pisces is also quite challenging because they do not understand each other enough to share much trust.

“The need Libra has to be accepted and liked by other people will be wrongly interpreted by Pisces, for they don’t understand how can someone’s self-confidence be that low,” the website claimed.

But even though the royal couple’s relationship didn’t last, the reason why they have maintained an amicable friendship has been revealed. Libra and Pisces are both selfless and they are also interested in the satisfaction of their partner.

This means that even after their relationship fails, they are able to stay on each other’s good side. And if they are able to move past the disrespect and the unrealistic expectations from each other’s personalities, it is possible for them to share real love with each other.

Prince Andrew and Ferguson tied the knot in 1986, but they separated in 1992. Their divorce was finalized in 1996, and they have two daughters together.
