In the case of an affair, the woman has violated the duty of fidelity between husband and wife, and also violated the public order and good customs of society, which will be morally condemned. In this case, both parties can reach an agreement on divorce and negotiate on the joint property of the husband and wife and child rearing. The faultless party can require the faultless party to share less property and bear the liability for compensation. If the agreement fails, the party can file a lawsuit for divorce to the people's court, but the faultless party should collect evidence in time, such as legal videos, repentance letters, recordings, etc.
