If you don't love anyone, you won't get hurt

Not loving anyone may indeed reduce the risk of emotional harm, but long-term avoidance of intimate relationships may lead to increased loneliness and social dysfunction. The pros and cons of emotional isolation depend on an individual's psychological resilience, social support system, and tolerance for loneliness.

Emotional isolation can avoid the pain caused by betrayal, separation, or rejection in the short term, especially for individuals who have experienced severe emotional trauma. The defense mechanism of the brain actively suppresses attachment needs and reduces sensitivity to others' emotions, which is more common in post-traumatic stress disorder or avoidant attachment personality. However, sustained emotional isolation may inhibit oxytocin secretion, affect emotional regulation ability, and increase the risk of depression. From an evolutionary perspective, humans naturally require social connections to maintain mental health. Long term lack of intimate relationships can activate the brain's "social pain" neural network, whose physiological response is similar to physical pain. Research shows that long-term loneliness may result in reduced gray matter in the prefrontal cortex, as well as impaired cognitive function and immunity. Some personality disorder patients, although actively choosing loneliness, often have a higher probability of self destructive behavior. If emotional attachment is avoided due to fear of harm, it is recommended to gradually rebuild a sense of security through psychological counseling. Mindfulness training helps to accept vulnerability, while group therapy can provide a low-risk emotional practice environment. Maintaining moderate social activities such as interest clubs or volunteer work can meet basic social needs without being deeply involved in relationships. Pay attention to observing whether there is sustained low mood or decreased social function, and seek professional evaluation if necessary.
