Surely not many. Again, not many. We are morally outraged by men who are cruel to women, but we tend to stay out of it when women are cruel to men. Traditionally, in most cultures, a woman seeks a commitment in a sexual relationship. And if she does not, or cannot get it, her family and friends stand ready to help her.
Emotions run high.
We are outraged by the man who sleeps with a woman but refuses to commit, especially when she is upset about it. He is using her, and we want him to shoulder his responsibilities or be gone. Family and friends can be more concerned than the woman is herself. Interested parties may try to convince her to leave the jerk while she complains about him but stays because she has feelings for him. The woman who cannot get a commitment is being exploited, and if she willingly goes along with it she is allowing herself to be exploited.
