As with other happiness-boosters, people who begin romantic relationships tend to eventually get used to—and perhaps begin to take for granted—much that is positive about being with a partner. Initially novel and exciting attributes, or shared experiences, may become less-appreciated over time. And among married couples, an increase in happiness during the “honeymoon period” is likely to revert back to the baseline. Efforts to recharge the relationship, such as seeking to incorporate variety into shared experiences, might help to counteract this process of habituation.
