You cannot directly check who your friend is chatting with on WhatsApp. The app prioritizes user privacy and does not allow access to someone else's chat history or contact list.
However, there are a few indirect ways you might be able to gain insights into your friend's WhatsApp activity:
- Observe their phone: If you have access to your friend's phone, you can see their recent WhatsApp notifications. However, this method is unreliable as notifications may not always be visible or may be cleared frequently.
- Pay attention to their behaviour: If your friend is constantly on their phone or seems distracted while chatting, it might indicate they are engaging in another conversation.
- Ask them directly: The most ethical and respectful approach is to simply ask your friend who they are chatting with.
Remember, it's essential to respect your friend's privacy and avoid any actions that could be considered intrusive or disrespectful.
