Why They Drift Away?

When a Loved One Suddenly Feels Like a Stranger: What Causes This Neglect?

Siam met Liza in the second year of university. For the first six months, Siam seemed to forget the whole world. A “good morning” message before she even woke up, hours of talking on the phone before going to sleep at night, Siam’s restlessness over every little problem of Liza – everything made it feel like Liza was the only star in his universe. But after seven months, suddenly everything changed. Replies to messages started coming after hours, phone calls decreased, “I’m busy” became the most familiar answer. At first Liza thought maybe it was study pressure. But a few weeks later she found out that a new person had come into Siam’s life – a new classmate, with whom he now spends all his time.

Liza’s story is actually the story of countless people. The roles in Liza and Siam’s story can also reverse – it may turn out that Liza started neglecting Siam, and at some point Siam discovered that someone had come into Liza’s life who is far more worthy than him. Almost everyone, at some stage of life, has gone through this feeling – a beloved person suddenly drifting away, becoming less attentive, turning neglectful. But why does this happen? Is it only a lack of love, or is there a deeper psychological and neurobiological explanation behind it?

The brain’s addiction to novelty

There is a well-known concept in psychology – “novelty seeking” or attraction to newness. The brain’s reward system, especially the ventral tegmental area and nucleus accumbens, responds unusually strongly to new stimuli. When someone comes into contact with a new person, dopamine secretion in the brain increases – just as it does with a new experience, a new place, or even buying something new. This dopamine-driven excitement temporarily makes a person overly focused on the new relationship, and the old, familiar relationship starts to feel comparatively “less exciting” – even though its depth or value does not actually decrease.

Researcher Helen Fisher’s work also supports this idea. According to her, the chemical reactions that occur in the brain during the initial phase of romantic attraction create behavior that closely resembles addiction. In this phase, people reduce their attention to old relationships because the excitement of the new relationship almost temporarily “takes over” the brain.

Attachment theory: Why some people easily drift away

According to psychologists John Bowlby and Mary Ainsworth’s attachment theory, the pattern of relationships formed in childhood determines how relationships are formed in adulthood. Those who have an “avoidant attachment style” feel a kind of discomfort after becoming deeply involved in a relationship, and unconsciously look for ways to create distance. The arrival of a new person becomes a kind of “escape route” for them – a temporary release from the responsibilities of the old relationship.

On the other hand, those with an anxious-ambivalent attachment often show excessive intensity at the beginning of a relationship – they become deeply involved quickly, express love quickly, but they do not have the emotional stability to sustain that intensity. As the relationship matures, they start to feel it increasingly heavy.

“Hedonic adaptation”: The diminishing value of familiarity

In behavioral economics and psychology, there is an established concept called hedonic adaptation – meaning, the more familiar something becomes, the less excitement we feel toward it; this is a natural adaptation process of the brain. A new car, a new job, even a new relationship – the initial enthusiasm for all of these decreases over time. This is not a personal failure, but an inherent feature of the human brain. The problem arises when someone uses this natural process as an excuse to seek new excitement instead of making efforts to sustain the relationship.

The psychological impact of neglect: How the brain reacts

An interesting point is that the experience of social rejection or neglect activates the same areas of the brain that are active during physical pain – especially the anterior cingulate cortex. This has been clearly shown in fMRI studies by researcher Naomi Eisenberger. This is why neglect is not just “emotional suffering”; the brain experiences it much like a physical injury. So feeling real pain in the chest due to someone’s neglect is not an exaggeration at all – it is a completely normal biological reaction.

Long-term neglect has a deep impact on self-esteem. Psychologist Mark Leary’s “sociometer theory” says that self-esteem is actually an internal measuring device that tracks our level of social acceptance. When someone is repeatedly neglected, this “meter” starts to drop, and the person begins to question their own worth – even though in reality the problem lies in the other person’s decision, not in their own competence.

Why some people never look back when they leave

Research shows that people who easily “exit” relationships often experience a kind of temporary contraction of empathy at the moment of decision-making. In psychology, this is called “moral disengagement” – mentally distancing oneself from the moral consequences of one’s actions so that less guilt is felt. This is not conscious cruelty; rather, it is a kind of defense mechanism of the brain that protects a person from the discomfort of hurting someone. But for the one who is being neglected, this explanation does not reduce the pain – it only makes it easier to understand that this is not their personal failure.

Psychological strategies to protect yourself

Psychologists say that when faced with neglect, the most important task is to examine one’s emotions without drowning in them. A core principle of cognitive behavioral therapy is that our feelings about an event depend on how we interpret that event. “They left me, so I must be unworthy” and “Maybe they couldn’t properly value me because of their own inner conflicts” – these two interpretations produce completely different psychological outcomes.

In addition, practicing “self-compassion” – not being a harsh critic of oneself but treating oneself like a compassionate friend – has been proven in research to accelerate psychological recovery.

The person who has been neglected should learn not to blame themselves, but to understand that the breakdown of a relationship is not always the failure of one side.

Final words

When someone neglects you, it is often a reflection of their own psychological instability, addiction-like craving for novelty, or fear of commitment in relationships – not proof of your worthlessness. Science says that the human brain is inherently attracted to novelty, and neglect is as much a biological experience as it is a psychological one. This understanding does not completely remove the pain, but it offers an important perspective – instead of blaming yourself, be compassionate toward yourself, and have the courage to walk away from any relationship where your worth is not recognized.
