He didn't deserve you. That's not just happy hour banter; it's backed by social science. Recent research in the Journal of Social Psychological and Personality Science shows that heterosexual men are 10 percent more likely to view their exes favorably than women, OZY reports. And that's rooted in history, experts say. A legacy of misogyny has left women "historically preconditioned to feeling like a victim," so if something was lacking in a relationship, "it's the guy's fault." But critics note the study focused on participants under 40, and maturity — and time — might put former flames in a better light.
