Physical violence is never an acceptable or appropriate way to resolve conflicts or express frustration in any relationship, including between spouses. It is not considered normal or healthy for a wife or anyone else to slap their partner.
In a healthy relationship, conflicts and disagreements should be resolved through open communication, understanding, and empathy. Physical violence not only causes harm but also erodes trust and respect between partners.
If there are issues in a marriage or any relationship, seeking help from a professional counselor or therapist can be beneficial to work through the challenges and develop healthier ways of communication and conflict resolution. It's essential to foster a relationship based on mutual respect, kindness, and support.
