Researchers argue over just how common infidelity is within the confines of a monogamous relationship, with some reports claiming it affects as many as half of all couples. Whatever the exact number, there's a high probability that you or someone you know has been cheated on -- it just may not have been for the reason you think.
The Monogamy Gap author Eric Anderson explained to HuffPost Live on Monday that people who experience a cheating partner often fall into a "victimization narrative" to explain why it happened. The idea is that "there's something so fundamentally wrong in the emotional relationship that one cheated," Anderson said. But according to his research, most infidelity has nothing to do with how much someone does or does not love the person they've committed to. He argues it has more to do with biology.
