Scorpios have a fear of abandonment. This sign is extremely protective and closed off, so when they finally let someone in, they're in for life. When the loyalty goes flying out the window and Scorpio gets left behind, it creates an intense emotional reaction, which further encourages the walls to go up and for them to have reservations with trust. We get it, Scorpio. You have to protect your heart, but are you making any effort to really try?
