When it comes to astrology, some of the signs are simply more loyal than others. These are by no means like that, and it will show as soon as the opportunity is presented with someone better than you.
Aries
The Aries are passionate, they like to be at the center of attention and they are enthusiastic about the person they are in a relationship with, but unfortunately, passion and enthusiasm quickly fade away, and after that, Aries looks for someone else to put them in the spotlight.
Gemini
They know exactly what they want ... until they change their mind. Gemini changes their mind quickly and often, so it's not unexpected that your Gemini suddenly realizes that they are not really that much into you.
Virgo
Perfectionists who know what they want and like having everything their way, but they will escape at the first sign that the person they are in a relationship with may be of flesh and blood.

Scorpio
Passionate at the beginning of the relationship, and precisely because of this passion, Scorpio often rushes into something that is not at all for them. Once they understand what is hiding under the surface, they give up and fall for someone else, guided by the same superficial passions.
