Psychological strategies for maintaining long-term friendships

Psychologists note that friendships often fade not through dramatic conflict, but through a gradual lack of attention and effort, a process known as relational maintenance. Research, including the Harvard Study of Adult Development, suggests that the quality of these relationships is central to long-term well-being.

To maintain connections, experts suggest small, low-pressure habits. One method involves sending ‘bids for connection’—messages that do not require a reply, such as sharing a photo or a thought, simply to signal that the person is on one's mind. Other strategies include following up on personal details shared by friends to demonstrate active listening and interest.

As individuals age, friendship dynamics often shift from being based on proximity to requiring more intentional effort. Challenges arise when one person feels they are the sole provider of effort in a relationship, leading to a natural withdrawal when the reciprocal energy is absent.
