8 phrases that truly close couples say: a Harvard psychologist

When words build a bridge across the chasm of daily worries

In the hustle and bustle of city life, when time is scattered between meetings, children and a multitude of messages, true intimacy in a couple seems rare, like a breath of clean mountain air. American psychologist Uman Nagy, who studied at Harvard, claims that couples who have achieved deep emotional unity do not just talk - they use eight special phrases that strengthen the connection, like invisible threads. These words are not magic spells, but, according to the expert, are woven from the fabric of trust, empathy and mutual respect. Studies of the psychology of relationships at prestigious universities confirm that regular use of such expressions increases the level of oxytocin - the hormone of attachment - and reduces the risk of a couple breaking up by 30-40%.¹ Are you ready to check if these phrases are present in your conversations with your loved one?

Who is Umana Nagy and why is her advice worth paying attention to?

Umana Nagy is not just a Harvard-educated psychologist, but a researcher who has been studying relationship dynamics for decades. Her career began in the labs of the prestigious university, where she analyzed data from thousands of couples, participating in projects like the long-running Harvard Study of Adult Development—one of the longest-running in the world, running since 1938.² This project found that the quality of relationships is a key factor in happiness and health, surpassing genetics or wealth.

Nagy, who now practices in California, is frequently quoted in publications like Business Insider and Forbes. Her approach is based on cognitive behavioral therapy and John Bowlby’s attachment theory. In a recent article for CNBC, she revealed eight phrases that she has observed distinguish “really close” couples from the average. These phrases have stood the test of time in clinical sessions and surveys. For example, in a 2022 study by the American Psychological Association, couples who regularly used expressions of empathy reported 25% higher levels of satisfaction.³

Expanding on the topic, let's pay attention to the global context. In Ukraine, where more than 60 thousand divorces are recorded every year (according to the State Statistics Service of Ukraine 2023), such advice is especially relevant. Local psychologists, such as Kyiv therapist Olena Kravchenko, confirm: in conditions of war and stress, couples who practice such phrases better overcome crises.⁴ These are not just words—they are a survival tool in a relationship.

The first phrase: “I am with you” is the basis of emotional support

The first phrase, according to Nagy, is "I am with you." This is not an empty reassurance, but a promise of presence in moments of pain or joy. Psychologists explain: such a phrase activates the parasympathetic nervous system, reducing the level of cortisol, the stress hormone. In the book "Attachment", Amir Levin gives examples of how couples in crisis who use these words restore trust in a matter of weeks.⁵

Real-life example: In a 2021 British study by Oxford University, couples who used the phrase "I'm with you" during conflicts resolved arguments 40% faster.⁶ In the Ukrainian context, this is especially valuable — a survey by the Institute of Demography of the National Academy of Sciences of Ukraine shows that 70% of couples in risk areas break up due to a lack of emotional support.⁴ Try saying this the next time your partner is stressed: the effect will be instant.

The second phrase: “Tell me more” is an invitation to the depths.

“Tell me more” is the second phrase that signals genuine curiosity. Nagy emphasizes that this is not an interrogation, but an expression of love. Research by relationship expert John Gottman shows that couples with high “emotional intelligence” ask such questions every day, which prolongs their marriage by years.⁷

Statistics: In a 2023 meta-analysis in the Journal of Marriage and Family, couples where one partner regularly said “Tell me more” had 35% less conflict.⁸ In Japan, where a culture of restraint dominates, therapists are implementing this phrase into programs for office workers, and the results are impressive: a 28% reduction in depression.⁹ For Ukrainians, accustomed to straightforwardness, this is a chance to move from superficiality to true intimacy.

The third phrase: “I noticed that you…” is the art of observation.

“I noticed that you…” is the third phrase. This is an acknowledgement of your partner’s efforts, often unnoticed. Nagy quotes clients: “When she said, ‘I noticed how tired you were after work,’ I felt seen.” Neuroscientists explain: such words stimulate dopamine, enhancing attachment.¹⁰

Scandinavian studies: In Sweden, couples with this habit have 50% lower levels of anxiety.¹¹ In Ukraine, analyses by psychological centers in Lviv show a similar effect among young families.¹²

The fourth phrase: “How do you feel about that?” is empathy in action.

“How do you feel about this?” is the fourth phrase that checks for emotional response. This is key to avoiding misunderstandings. A 2022 Harvard study found that couples who practice this are less likely to complain about loneliness in their marriage.²

Experiments in Australia show that regular use reduces the risk of divorce by 22%.¹³ Locally, in Odessa consultations, this has become the standard for veteran couples.¹⁴

Fifth phrase: "Thank you for..." - gratitude is like glue

“Thank you for…” is the fifth phrase that builds positivity. Nagy recommends personalizing it: “Thank you for being so patient.” Gratitude expert Robert Emmons proves that daily practice increases happiness by 25%.¹⁵

In Canada, a 2023 study showed an effect on long-term couples.¹⁶

Sixth phrase: “Sorry, I was wrong” — the power of vulnerability

“I’m sorry, I was wrong” is the sixth phrase that dissolves resentment. Bowlby considered this the foundation of secure attachment.⁵

In the US, couples with apologies have 60% higher stability.¹⁷

Seventh phrase: “I am proud of you” – ego boost

"I'm proud of you" is the seventh phrase that motivates. Studies show an increase in self-esteem.¹⁸

Eighth phrase: “I love you not for…” — unconditional love

"I love you not for..." - the eighth phrase cements the connection. Harvard data: the key to longevity.²

Practical tips: how to implement phrases in life

Start small: choose one phrase per week. Apps like Couple track your progress. Ukrainian psychologists recommend combining it with meditation.⁴ Results: deeper intimacy over months.

The consequences of ignoring: what the numbers say

Without these phrases, couples risk isolation. Statistics: 41% of divorces are due to communication.¹⁹ In Ukraine — 55%.⁴
