Why Do Women Cheat in Relationships

The third top reason for women cheating, according to the study? It was just situational. Things like being drunk and "not thinking clearly."

"Everyone makes mistakes. Sometimes, affairs happen because of opportunity," Nelson adds. "Women can act impulsively and then regret it." In other words, it's entirely possible there isn't much deeper meaning aside from an opportunity that they weren't able to pass up in the moment.
