Once again, we can thank our hormones for getting us into relationship trouble. According to new research by Kristina Durante of The University of Texas at San Antonio, women who are ovulating may delude themselves into believing that the suave and unattainable cad would make a better partner than Mr. Nice and Available. Durante refers to the phenomenon as "ovulation goggles." Before you fall too hard for that wayward playboy, it might be wise to let your wily hormones run their course.
