Scorpio may not be the sweetest of all zodiac signs, but they are extremely loyal. As loyalty should be returned by loyalty, the thing that gives Scorpio the creeps is being betrayed by the ones they trusted, mostly because they are not too eager to open up to people.
Whenever their trust is betrayed, it will take years to restore the order of things in a relationship. Not only the offender will suffer – Scorpios are unwilling to forgive, but they will be tortured by the loss of a friend just as much. This is why they are so afraid of losing confidence in people.
