It might be difficult to summarize all the opinions. But I would like to ask,

1. Have you ever met infidelity in your friends or other people?

2. How did he or she deal with such affair and the relationship with his or her mate?

3. Do you think infidelity is just private affair, or it is immoral and should be condemned by the public, or it might violate some laws and should be punished?

Why I ask these questions? I was evoked by the "Lin Dan affair" several days ago. But when I calmed down and thought about this issue, I found that infidelity has been quite a close phenomenan to me. Some of my friends were victims of infidelity of their partners, some of my friends made extramarital deeds and cheated their partners or have hurt them, some of my friends cheated each other with their partners in relationship. 

In my living town of China, as I observed, infidelity is immoral and condemned by many people. In some circumstances people might use the Marriage Law to protect their rights. But I have found out something interesting or even ridiculous. The infidelity of a male is also condemned by the public, but is much acceptable and forgivable than the same thing of a female. If a woman found her husband had extramarital affair, she and her relatives might blame the husband, but finally if the husband admitted his mistake and promised amendment, the wife were more likely to forgive him and not to divorce. But if the same thing was conducted by the wife, finally the relationship would be irreparable.

I just wonder how you view this in your culture. Welcome to discuss it.
