Some women choose to live without a partner, a decision that challenges common assumptions about relationships being a necessary stage in life. Bella DePaulo, a psychologist with a doctorate from Harvard and a specialist in single life for several decades, has never wanted to live in a relationship. In an opinion piece published in HuffPost, she explains that her choice is neither a romantic disappointment nor a surrender, but a path that fully suits her and brings her happiness. She uses the term "single at heart," indicating that some people thrive in single life because it meets their deep needs. DePaulo emphasizes that people who choose this lifestyle value the freedom to decide their schedule, finances, place of residence, and projects. This autonomy is not seen as a consolation but as a true source of fulfillment. Her research includes hundreds of testimonies and analysis of scientific work on single life, showing that many single adults report life satisfaction, with this satisfaction increasing after the age of 40. DePaulo also addresses the common belief that aging alone inevitably leads to loneliness. However, her research indicates a more nuanced story, showing that single people often invest more in other important relationships, such as friends, neighbors, siblings, or colleagues. This diverse network contributes to their satisfaction. While single life does not necessarily make people happier than being in a relationship, it highlights that there are multiple ways to achieve happiness. For some, it comes through a romantic relationship, while for others, it arises from the freedom to build their existence differently.
