If you quarrel with your husband, you should try your best to avoid escalating the contradiction, especially if a third party is involved. If your father-in-law comes in and beats your husband, you should take immediate action to prevent further violence.
Here are some measures you can take:
1. Call the police: If you feel that you or others are in danger, you can call the local emergency number, such as 1 10, to report domestic violence to the police. The police will take necessary measures to protect you and your family.
2. Seek help: If you and your family have suffered from domestic violence, you can seek help from local social service agencies, domestic violence assistance centers or women's aid organizations. These institutions can provide the support and resources you need.
Talk to your father-in-law: If you think his behavior is inappropriate, you can talk to him, express your opinion and try to solve the problem. You can tell him that violence between family members is unacceptable and ask him to respect your privacy and rights.
Talk to your husband: You can talk to your husband and tell him your feelings and needs. You can express your concern and support and discuss how to avoid similar situations from happening again.
No matter what action you take, remember that your safety and health are the most important. If you feel that you can't handle this problem, don't hesitate to seek professional help.
