I can provide some insight into this behavior.
Wanting a partner to turn around or give visual confirmation that they are not talking to someone else while on the phone could stem from various emotions or reasons. Some individuals may have trust issues or insecurities that lead them to seek reassurance in this manner. It could also be driven by past experiences, communication challenges, or a lack of confidence in the relationship.
While it's natural for people to feel the need for reassurance and trust in a relationship, it's essential to address the underlying issues rather than trying to control or monitor a partner's actions. Open and honest communication is crucial for building and maintaining trust. If one partner feels the need to constantly verify the other's actions, it may be an indication that there are deeper trust issues that need to be addressed and resolved together.
Healthy relationships are built on trust, mutual respect, and communication. If either partner feels the need to resort to controlling or monitoring behaviors, it's essential to seek help, such as couples therapy, to work through any underlying issues and establish a more secure and trusting relationship.
