“ It wasn't only my friends who suffered from female rivalry. I remember when I was just sixteen years old, during spring vacation, being whisked off to an early lunch by my best friend's brother, only to discover, to my astonishment and hurt, that she was expecting some college boys to drop by and didn't want me there to compete with her. When I started college at Sarah Lawrence, I soon noticed that while some of my classmates were indeed true friends, others seemed to resent that I had a boyfriend. It didn't help that Sarah Lawrence, a former girls' school, included very few straight men among its student body--an early lesson in how competing for items in short supply often brings out the worst in women. In graduate school, the stakes got higher, and the competition got stiffer, a trend that continued when I went on to vie for a limited number of academic jobs. I always had friends and colleagues with whom I could have trusted my life--but I also found women who seemed to view not only me but all other female academics as their rivals. This sense of rivalry became more painful when I divorced my first husband. Many of my friends I depended on for comfort and support suddenly began to view me as a threat. Some took me out to lunch to get the dirt, then dropped me soon after. I think they found it disturbing that I left my unhappy marriage while they were still committed to theirs. For other women, the threat seemed more immediate--twice I was told in no uncertain terms that I had better stay away from someone's husband, despite my protests that I would no more go after a friend's husband than I would stay friends with a woman who went after mine. Thankfully, I also had some true friends who remained loyal and supportive during one of the most difficult times of my life. To this day I trust them implicitly, with the kind of faith you reserve for people who have proved themselves under fire. But I've also never forgotten the shock and disappointment of discovering how quickly those other friendships turned to rivalries. ”
