If You Think You Have a Frenemy, Ask Yourself These 10 Questions

The word "frenemy" usually conjures up the image of fictional mean girls like Regina George—someone who's not exactly a trustworthy friend yet not quite an all-out enemy. Of course, the word is a combination of "friend" and "enemy"—but what does it really mean? To get an expert's perspective, we asked psychotherapist Jeremy Bergen, MS, LCPC, all our burning questions—starting with the most basic one: Who is a frenemy?

"A frenemy is a person in your life where there's some type of rivalry under the surface of a friendship," Bergen tells us. "This rivalry may arise from unresolved conflict between two people, competitiveness that develops over the course of the friendship, jealousy by one or both parties, or it may be a manifestation of psychological issues by one person."

Here's what you need to know about the psychology of a toxic friendship, including the identifying signs, the mental and emotional consequences, and how to navigate the next steps.
