No, under no circumstances is it acceptable or justifiable for a husband, or anyone else, to physically abuse their spouse or partner for any reason, including if they are caught with a boyfriend or for any other perceived transgression. Physical violence is illegal, immoral, and a violation of a person's human rights.
If there are issues in a relationship, such as infidelity, they should be addressed through open communication, understanding, and seeking professional help if needed. Resorting to violence is not an appropriate or productive way to deal with conflicts.
In situations where there are problems or concerns within a relationship, it is essential to seek assistance from a counselor, therapist, or mediator to work through the issues in a healthy and respectful manner. Additionally, if someone is experiencing abuse, they should seek help from a domestic violence support organization, family, or friends to ensure their safety and well-being.
Remember, violence is never the answer, and everyone deserves to be treated with respect, dignity, and kindness in any relationship.
