Repeat this 20 times. Ask yourself whether deep down you believe that remembering the relationship preserves it in some way. Embrace the reality that longing does not connect you and write a new belief code, such as: “I have never left a relationship that would have made me happier than I am now.” “This is a person of great worth, but not to me.”

Each of us probably has 10,000 people we could feel a similar connection to---don’t mythologize as “one and only” someone who actually might have been unremarkable.
