How Resentment Builds in Relationships — The Real Psychology
Last reviewed by the Men Women Psychology editorial team.
The evidence
What the research actually shows
John Gottman's research describes a shift he calls negative sentiment override, where a partner becomes so primed to see the worst that they read neutral or even positive behavior as hostile. Gottman and Levenson (1992) found that couples heading toward dissolution tended to show this corrosive pattern, in which accumulated negativity colors interpretation. Resentment appears to be less about one big betrayal and more about this slow tilt of the emotional lens.
Much of the buildup traces to small missed moments. Gottman's work on 'bids' for connection suggests that when one partner reaches out and the other consistently turns away, the unmet reaching gradually breeds disappointment. Over time, repeated turning-away tends to leave a residue of feeling unseen, which can harden into resentment even without any dramatic conflict.
Investment and fairness also play a part. Drawing on exchange-oriented research like Rusbult's investment model (1980), people tend to track what they put in and get back from a relationship. When one partner perceives a chronic imbalance — doing more, sacrificing more, being appreciated less — score-keeping can set in, and the sense of unfairness tends to feed lingering resentment on either side.
The mechanism
Why this happens
Resentment often grows because hurts go unspoken. When a partner suppresses small grievances to keep the peace, those feelings rarely disappear; they tend to accumulate quietly until the relationship feels heavy. Each swallowed complaint can leave a trace, and the sum of many small unaddressed moments can outweigh any single argument.
Negative sentiment override makes the problem self-reinforcing. Once someone expects the worst from a partner, attention and memory tilt toward confirming evidence, so ambiguous actions get read uncharitably. This biased interpretation tends to generate fresh grievances, which deepen the negative lens further, creating a loop that is hard to exit without deliberate effort.
A sense of inequity sharpens it. When one partner feels they consistently give more than they receive — whether in emotional labor, chores, or care — the perceived unfairness can curdle into resentment. Because partners often track their own contributions more vividly than each other's, both people can simultaneously feel underappreciated and overextended.
In practice
What this looks like in real life
A partner who repeatedly mentions feeling overwhelmed and is met with distraction or a quick fix may stop bringing it up. The complaints go quiet, but the disappointment does not — months later it can surface as cold distance or sharp criticism that seems disproportionate to whatever triggered it.
One person may keep a private tally of everything they handle that the other does not notice. Even when no fight occurs, that running ledger can color how they greet their partner each day, so a neutral comment gets heard as one more sign of being taken for granted.
Couples in negative sentiment override often describe how even kind gestures stop landing. An apology sounds insincere, a compliment feels like manipulation, and help is read as interference — because the underlying lens has shifted, the same act that once would have warmed them now reinforces the grievance.
Myth vs. evidence
What most people get wrong about this
A common misconception is that resentment comes mainly from big betrayals. Research suggests it more often accumulates from the steady drip of small unmet needs and missed connections, which is why couples can feel deeply resentful without being able to point to any single dramatic event.
Another mistake is assuming that avoiding conflict protects the relationship. Suppressing small grievances to keep the peace tends to let them compound, so the very habit meant to prevent friction can quietly feed the resentment that erodes the bond over time.
Why it matters
What this means for relationships
Couples tend to do better when they address small hurts early and gently rather than storing them up. Raising a concern with a soft start-up, before it hardens, appears to prevent the slow accumulation that drives resentment, and it gives a partner a chance to repair before the lens turns negative.
Rebuilding goodwill often means deliberately countering negative sentiment override — noticing and naming a partner's positive efforts, responding to their bids, and reconnecting around appreciation. Because the pattern is mutual, both partners contributing to repair tends to matter more than either one waiting for the other to start.
Where it varies
The nuance
These dynamics are tendencies observed across many couples, not fixed laws, and individuals vary widely. Janet Hyde's gender similarities hypothesis (2005) reminds us that men and women are far more alike than different on most psychological measures; both partners are equally capable of feeling resentful and of accumulating unspoken hurts.
Who feels resentment and why depends heavily on context. Attachment style, stress, the actual fairness of the division of labor, and each person's communication habits all shape the picture. Some couples carry low-level resentment for years; others repair quickly. The presence of resentment signals a need for repair, not necessarily a doomed relationship.
Questions people ask about this
What actually causes resentment to build in a relationship?
Research suggests it usually accumulates from many small unmet needs, missed bids for connection, and unspoken hurts rather than from one big event. Over time these add up and can shift how partners interpret each other, tilting the relationship toward a generally negative emotional lens.
Is resentment a sign the relationship is over?
Not necessarily. Resentment tends to signal that needs have gone unmet and repair is overdue, not that the bond is beyond saving. Many couples interrupt the pattern by addressing grievances, rebuilding appreciation, and responding to each other's bids before the negativity becomes entrenched.
What is negative sentiment override?
It is a term from Gottman's research for when a partner becomes so primed to expect the worst that they read neutral or even positive actions as hostile. Once this lens sets in, ordinary gestures stop landing and fresh grievances form easily, which can deepen resentment further.
Does keeping score make resentment worse?
It often can. When one partner feels they consistently give more than they receive, a private tally of unfairness can form. Because people tend to notice their own contributions more vividly than a partner's, score-keeping can leave both people feeling underappreciated and quietly resentful.
Can avoiding conflict cause resentment?
Research suggests it often can. Suppressing small complaints to keep the peace tends to let them accumulate rather than disappear. Many couples find that gently raising concerns early prevents the slow buildup that turns minor disappointments into lasting resentment over months or years.
How can couples reduce resentment that has already built up?
Approaches that tend to help include naming hurts gently, responding to a partner's bids for connection, and deliberately noticing positive efforts to counter the negative lens. Because resentment is usually mutual, both partners taking part in repair generally works better than one person trying alone.
