That may be why it is difficult for you to trust the first time. Maybe for that reason, your circle of people of full trust is so small, and you know it. For you, being someone else is not the same as being a FRIEND. It is not the same to be a partner to be THE PARTNER, and you know it. Whoever has a key to access your heart and your deepest self does not know it but has something unique, special, invaluable, and something that will always be worth fighting for.
Seriously, Scorpio, you will never be willing to extend a copy of those keys to everyone who claims to be your friend. You will never put aside your cunning and unprotect your heart that way because you know what? That years and experiences have made you a very wise person, and thanks to this combo, you already know that it is better to distrust in time than to sin and give confidence to someone who does not deserve that position. Whoever makes a hole in your heart does not know but wins the best prize that the visa can give you. You know it, Scorpio.
