The novelty that triggers dopamine doesn’t go on forever. When it comes to love, the loss of passionate romance will always happen eventually, and then comes a choice. We can transition to a love that’s fed by a day-to-day appreciation of that other person in the here and now, or we can end the relationship and go in search of another roller coaster ride. Choosing the dopaminergic kick takes little effort, but it ends fast, like the pleasure of eating a Twinkie.
