When people talk about \u201cchemistry\u201d or \u201cthe spark,\u201d they\u2019re often describing dopamine. Dopamine is a neurotransmitter linked to pleasure, reward, motivation, and anticipation. In romantic relationships, dopamine surges during early attraction, creating excitement, focus, and emotional intensity. But while dopamine plays a powerful role in bringing two people together, it is not what sustains long-term love.<\/p>\n
In Gottman\u2019s framework, lasting love tends to unfold in three broad phases: an initial limerence phase driven by intense chemistry, a trust phase in which partners learn whether they can rely on each other, and a commitment phase in which they actively choose the relationship over time.<\/p>\n
According to Dr. John Gottman\u2019s decades of research with couples in the Love Lab, successful relationships are built on emotional attunement, trust, and friendship\u2014not just neurochemical highs (The Seven Principles for Making Marriage Work<\/em>).\u00a0<\/p>\n Dopamine is often described as one of the brain\u2019s \u201creward chemicals.\u201d It becomes active when we experience something pleasurable or anticipate something rewarding.<\/p>\n In relationships, dopamine fuels infatuation, increases energy and focus on a partner, heightens desire and excitement, and reinforces bonding through positive experiences\u00a0<\/p>\n Early in dating, dopamine can make ordinary interactions feel extraordinary. A text message triggers anticipation. A glance feels charged. The brain quickly associates this person with potential reward, which helps explain why it is so hard to stop thinking about them.\u00a0<\/p>\n Dopamine is also sensitive to novelty and unpredictability. As a relationship becomes more predictable, those sharp dopamine spikes naturally decrease\u00a0. Studies of long-term couples suggest this is a normal adaptation, not a sign that love is gone.<\/p>\n Gottman describes the first phase of love as a limerence phase (Phase 1 in \u201cThe 3 Phases of Love\u201d). It corresponds to what most people think of as the honeymoon period: dopamine\u2011driven attraction, strong longing, and a narrowed focus on the other person. Brain imaging shows strong activation in reward regions when people in early romantic love see images of their partner.<\/p>\n From a Gottman perspective, limerence looks like positive sentiment override\u2014the phase in which partners interpret each other generously. Minor irritations are minimized, and people assume good intent. Dopamine in relationships helps create this glow, but in Gottman\u2019s model it is only the first phase of love.<\/p>\n What matters for the future of the relationship is what happens as couples move out of limerence into the second phase: building trust. If you are in this high\u2011dopamine stage and want to look beyond chemistry, Gottman\u2019s \u201cHow to Plan a Successful Relationship\u201d offers concrete questions about values, conflict, and life dreams:\u00a0<\/p>\n .<\/p>\n When dopamine levels stabilize, many couples notice less automatic excitement, more irritation, and a decline in sexual novelty. This is often the point when conflict surfaces more regularly.<\/p>\n This is also where Gottman\u2019s second phase\u2014trust\u2014either solidifies or erodes (Phase 2 in \u201cThe 3 Phases of Love\u201d). In this view, trust is built through repeated experiences of \u201cyou are there for me\u201d during stress, disappointment, and everyday needs.<\/p>\n Across thousands of couples, Gottman has identified four interaction patterns\u2014criticism, contempt, defensiveness, and stonewalling\u2014as strong predictors of relationship breakdown, known as the Four Horsemen.<\/p>\n These patterns are more likely to appear when couples have leaned on dopamine\u2011driven excitement but lack conflict\u2011management skills. Each episode of harsh criticism or emotional withdrawal sends the message \u201cI am not safe with you,\u201d and slowly undermines the trust phase.<\/p>\n Without deliberate effort, partners begin \u201cturning away\u201d from emotional bids instead of turning toward them\u2014a core Gottman concept. At this point, the issue is not that dopamine has disappeared, but that a long-term love relationship requires emotional attunement, trust\u2011building behavior, conflict\u2011resolution skills, and shared meaning. Dopamine may start the relationship. Skills and daily practice of small \u201cthings\u201d sustain it. (For practical strategies grounded in Gottman\u2019s research, see \u201cConflict Resolution in Relationships\u201d).<\/p>\n .<\/p>\n While \u201cchemistry\u201d fuels early passion, both neuroscience and Gottman\u2019s long\u2011term data suggest that stable, fulfilling love rests on something deeper. Research on couples who report being \u201cin love\u201d after many years finds continued activation in reward circuits, but now combined with brain regions associated with calm and secure attachment.<\/p>\n Couples who thrive over time tend to live out what Gottman calls the Sound Relationship House.<\/p>\n In Gottman\u2019s three\u2011phase view, this is the commitment phase (Phase 3 in \u201cThe 3 Phases of Love\u201d). Commitment means more than legal status; it is the ongoing choice to invest in the relationship, protect it from outside threats, and prioritize the partnership when life gets complicated.<\/p>\n The Sound Relationship House framework shows how specific behaviors support trust and commitment in daily life. For a deeper dive into Love Maps, see \u201cThe Sound Relationship House: Build Love Maps\u201d:\u00a0<\/p>\n .<\/p>\n Dopamine is powerful. It brings people together. It motivates pursuit. It creates exhilaration. But sustainable love is not built on constant highs. It is built on friendship, trust, emotional responsiveness, and shared meaning\u2014the very elements Gottman\u2019s research has highlighted for decades. Dopamine may help ignite limerence. Trust is built through daily small, reliable responses. Commitment is the decision to keep showing up.<\/p>\n If you want to move from chemistry to deeper emotional connection, a concrete next step is to strengthen your emotional vocabulary.
