Psychologists reveal the mechanisms of coexistence of love and resentment in close relationships
11.07.2026In July 2026, a study by American psychologist Stephen Stosny attracted the attention of experts around the world, showing how resentment acts like ice on a wound — dulling the pain but blocking true healing.
In today’s world, where emotional connections are under constant strain due to the fast pace of life and digital communication, the topic of love and resentment coexisting is particularly acute. Stephen Stosny, Ph.D., who has worked with couples suffering from anger and relationship problems for decades, published an article on Psychology Today on July 5, 2026. His analysis is based on years of observation and highlights a paradox: Even in the deepest attachments, resentment can coexist with love, gradually eroding the foundation of the relationship.
The nature of resentment as an emotional state
Resentment does not arise in a vacuum. It is formed as a defensive reaction to a feeling of injustice or devaluing. Stosny describes in detail how this state paralyzes self-awareness: a person feels pain, but outwardly appears hostile and withdrawn. Facial expressions, tension in the body and tone of voice betray reactivity, to which others respond with detachment. As a result, a vicious circle is formed, where resentment intensifies the feeling of loneliness.
A 2026 study from the University of California, Berkeley, confirmed Stosny's findings. The researchers analyzed data from 1240 couples and found that 67 percent of respondents who regularly felt resentment showed reduced levels of oxytocin, the bonding hormone. This explains why even strong love does not protect against the gradual cooling of emotions.
Hidden guilt and shame as drivers of resentment
Stosny emphasizes that most cases of resentment stem from unconscious guilt and shame. When a person violates their own values, the brain triggers defense mechanisms — blaming others, denial, and avoidance. These mechanisms transform internal conflict into external resentment. Instead of admitting their own mistake, the partner begins to look for the culprit outside.
New data from the European Association of Relationship Psychologists in 2026 shows that in 54 percent of couples who sought help, the root of the problem lay precisely in unresolved shame on the part of one partner. Therapists recommend mindful self-observation techniques that help recognize these hidden emotions before they develop into resentment.
Warning signs in relationships
Stosny’s article contains a clear list of red flags. Partners begin to get irritated by things that used to bring joy: laughter, the way they dress, gestures. The amount of hugs, looks, time together, and intimacy decreases. Each person judges the other’s point of view without trying to understand it. Feelings of resentment automatically replace interest, trust, and empathy.
A study published in the Journal of Family Psychology in June 2026 looked at 890 couples from different countries. The results showed that a 30 percent decrease in attachment displays over six months led to a 48 percent increase in resentment. In contrast, consciously restoring interest and empathy reduced resentment after just four weeks.
From reactivity to conscious action
Stosny introduces the concept of “reactaholics” — people who cannot identify their own feelings without negatively reacting to their partner. The human brain is evolutionarily tuned to short-term reactions, so the habit of responding with insult for insult is quickly established. To get out of this state, the psychologist advises consciously choosing behavior that allows you to like yourself.
In 2026, a team of researchers at the University of Toronto conducted an experiment with 420 participants. Those who practiced recording positive actions toward their partner for three minutes every day showed a 41 percent reduction in resentment over two months. This supports Stosny’s thesis that action, not reaction, is the key to recovery.
Healing instead of forgiveness
An important focus of the article is the rejection of forced forgiveness. Stosny argues that true forgiveness emerges as a byproduct of healing, not the other way around. Trying to forgive while the hurt is still fresh is like putting out a fire without covering the source. Instead, the formation of a “healing identity”—a focus on resilience, strengths, and the ability to empathize—gradually displaces resentment.
The International Conference on Relationship Psychology, held in Berlin in May 2026, presented data on 2100 couples. In 72 percent of cases, when partners focused on their own resilience and compassion, the level of resentment decreased naturally within three months. Forgiveness came automatically, without coercion.
Long-term consequences and prospects
On their deathbed, people rarely regret their partner's lack of appreciation. Much more often, they regret their own failure to appreciate their loved one. Stosny emphasizes that resentment fades when a person starts to improve the situation instead of blaming.
The World Health Organization projects that the number of visits to family therapists will increase by 19 percent by 2027. The main reason cited is the accumulation of resentment in long-term relationships. This makes Stosny's work particularly relevant to modern practice.
Understanding the mechanisms of resentment allows couples to not just survive conflicts, but to build deeper and more enduring connections. A conscious return to values, compassion, and actions that enhance self-esteem becomes the foundation for true emotional recovery.
