Gemini men have the initial belief that "if someone is attractive, they want to get along with anyone." Even if they have no intention of cheating, they may end up developing feelings or being liked by the woman they are interested in while talking to her.
Gemini is sociable and can easily get along with others from the first meeting, but it is rare for them to show their true selves and really open up. Even if they cheat, it is likely to be just a one-time thing. They won't build deep relationships that lead to serious affairs, and they often engage in flirting without their partner noticing.
