What?? I think women are forgiven more easily for infidelity than men. Again, double standard, since women are "weak" and "emotional" and therefore easily plied into doing things they normally wouldn't.
That said, some women are way too forgiving of men who cheat on them, letting them do it repeatedly. I have one friend whose boyfriend cheated on her four times
with the same girl, and even then she was still begging him not to break up with her. She finally came to her senses and dumped his ass, but still.
