Since nostalgic events are often associated with certain people, nostalgia can easily bring us closer to others. Example: Watching Disney Channel Original Movies with your besties during a sleepover. Plus, many researchers refer to nostalgia as a psychological resource, since it can make us feel safe and loved. However, when you start to remember past relationships, that’s when things can go downhill. If you reminisce on time spent with your ex, it could make it hard for you to move forward and start a new relationship.
