Scorpio and Cheating:
What would drive a Scorpio to Cheat?
Love is very important to Scorpios. In fact, they're very loyal and can be pretty possessive with their partner. However, if Scorpios end up cheating, more than likely, it is because their partner cheated first.
Scorpios can get very vindictive. An eye for an eye. You hurt me, I hurt you. Another reason could be that Scorpio is not getting enough emotional connection with their partner, or if they find someone they have an emotional affinity with.
