The appropriateness of your husband's behavior depends on the context and the intent behind his actions. While it is common for people to use social media platforms like Facebook to connect with friends and acquaintances, searching for random girls can be concerning if it makes you uncomfortable or if there are any suspicious or inappropriate intentions.
It's essential to communicate openly and honestly with your husband about your feelings and concerns. Sometimes, individuals may engage in seemingly innocent actions without realizing how they could be perceived by their partners. An open conversation can help clarify his intentions and provide reassurance, or it can address any potential issues that need to be addressed within the relationship.
If you feel that his behavior is crossing boundaries, causing distress, or leading to distrust in your relationship, it's important to discuss these feelings and consider seeking the assistance of a professional counselor or therapist to help navigate the situation together.
Ultimately, every relationship is unique, and what is considered "normal" behavior can vary. It's essential to establish clear boundaries and mutual respect within the relationship to ensure both partners feel comfortable and secure.
