When encountering easy-to-fake signals of commitment, such as verbal declarations of love, women show suspicion

Sexual Conflict in Human Mating. David M. Buss. Current Directions in Psychological Science, http://journals.sagepub.com/doi/abs/10.1177/0963721417695559

Abstract: Despite interdependent reproductive fates that favor cooperation, males and females exhibit many psychological and behavioral footprints of sexually antagonistic coevolution. These include strategies of deception, sexual exploitation, and sexual infidelity as well as anti-exploitation defenses such as commitment skepticism and emotions such as sexual regret and jealousy. Sexual conflict pervades the mating arena prior to sexual consummation, after a mating relationship has formed, and in the aftermath of a breakup. It also permeates many other social relationships in forms such as daughter-guarding, conflict in opposite-sex friendships, and workplace sexual harassment. As such, sexual conflict constitutes not a narrow or occasional flashpoint but rather persistent threads that run through our intensely group-living species.

When encountering easy-to-fake signals of commitment, such as verbal declarations of love [...] women show suspicion or dubiety. [...] Women, more than men, tend to regret acts of sexual commission (e.g., having sex while drunk).

My comment: could it be for the anticipation of possible consequences, like disease and pregnancy?
