The main reason a woman might blame the OTHER woman for her man’s infidelity is simple – it’s just easier to deal with. While a woman may have known that something was wrong for a long time, no one wants to believe that their partner COULD or WOULD cheat on her. We believe that he loves us, so blaming the other woman is easier than actually acknowledging that something is wrong with the relationship. In our minds, she had to have seduced him or made the first move. Most women see cheating as a form of rejection, and since no one wants to be rejected by their partner, it’s easier to focus all of the pain and anger on HER rather than on him and a bad relationship.
