Tension reduction is a predominant principle that contributes to the formation of human interactions. This principle acts as a self-organizing process; it indicates that social communications are established based on the tendency towards balanced states. Interesting questions that follow concern what parameters have a pivotal role in the social network dynamics. An appropriate answer seems to lie in the history of relationships. In order to investigate some history (memory) effect on social networks, we introduce a temporal kernel function into the Heider conventional balance theory, allowing for the quality of past relations to contribute to the evolution of the system. We have found out that memory sometimes withstands the quick evolution of the network and eventually preserves the system in unstable but long-lived states namely, glassy states. Under such circumstances, for various time intervals, the system has no tendency to evolve towards global or local minima. In contrast to jammed states (local minimum states), in which systems only experience negative energies, glassy states can occur in positive energy states, thereby imposing instability to and keeping stress in the system.
