"If you think someone is cheating just leave," advised another. "Don’t play games like you’re Sherlock Holmes. Usually the accuser is the guilty one anyway." And a third said: "So is a woman if she gives the same answer." Some were more on board with her claim, with one saying: “I agree because if he was innocent he would be aggressively defending himself."
