Geminis are more prone to romantic straying since they are often bored. The Twins, who are indecisive and quick to change their minds, have a difficult time deciding what they want.
They're a classic case of attempting to have their cake and eat it too. This can occasionally emerge as emotional or physical cheating. If they are caught, they almost never apologize.
Instead, they find a way to make it their fault. You weren't supplying. You were ignoring their requirements. Keep an eye out for a Gemini. They'll stab you in the back and then find a way to blame you for it.
Scorpios are an entirely inappropriate sign. They have powerful libidos and little tolerance for (or are simply terrified of) emotional vulnerability.
Commitment frightens them, therefore it's not surprising that they'll poison a relationship if they sense themselves growing too close to someone.
They can also be quite harsh and spiteful. If they are scorned or hurt, they will not hesitate to retaliate, generally in a provocative manner.
A Sagittarius literally cannot stop flirting with anybody and everyone. They, like Scorpios, are a romantic sign who finds great pleasure and fulfillment in being desired.
They are usually the life of the party, someone that everyone gravitates toward and enjoys spending time with. As a result, they typically have a plethora of suitors. It's not difficult for them to succumb to temptation.
A Sagittarius literally can’t stop themselves from flirting with anyone and everyone. They, like Scorpios, are a sensual sign and derive a lot of pleasure and validation from being wanted.
