heard from women whose colleagues, best friends, and sisters had stolen their boyfriends and husbands. I talked with women whose fear of female rivalry was so strong that they chose to live in small towns, “so there would be less competition”; women who avoided certain parties “because I don’t want my husband to meet too many single, beautiful women.” I heard about girlfriends dropping a woman when she snagged a promotion at work, or finally found a great guy, or even when she became pregnant.
