Most relationship friction doesn’t come from dramatic betrayals or life-altering events. It comes from smaller, repeated patterns – the things that quietly chip away at trust, warmth, and goodwill over months and years. Stress in romantic relationships is an all-too-common phenomenon that has detrimental effects on relationship well-being, with stress leading to negative interactions between partners and ultimately decreasing relationship functioning. What’s striking is how often couples can pinpoint the exact behaviors that drain them – even when they struggle to stop doing them.
The behaviors below aren’t about catastrophic failures. They’re the everyday habits that couples, when honest with themselves, say simply aren’t worth the toll they take. Depending on a couple’s response, chronic life stressors and relational patterns can threaten a relationship enough to result in dissolution – though a stressor that is well-negotiated in one relationship may be the death-knell of another. Recognizing these patterns is often the first step toward changing them.
1. Stonewalling and Shutting Down During Conflict

Stonewalling is when someone emotionally shuts down and withdraws from an interaction. It can appear as though they are ignoring their partner or pretending they aren't there – but what's really happening is that the person is experiencing diffuse physiological arousal, also known as being flooded, meaning they are overwhelmed to the point where their brain can't function normally. The problem is that, regardless of the internal cause, the impact on the other person can be severe.
Research by Dr. John Gottman shows he can predict divorce with over 90% accuracy, and stonewalling is one of his "Four Horsemen of the Apocalypse." The person being shut out experiences what researchers call "relational trauma" – feelings of abandonment, confusion, and powerlessness – while studies show both partners end up with lower intimacy, reduced communication skills, and higher levels of depression. For most couples, the cost far exceeds whatever temporary relief stonewalling provides.
2. Using the Silent Treatment as a Weapon

The silent treatment feels like a childhood game where everyone ignores the target and pretends they don't exist. It's an intentional refusal to acknowledge the other person, often intended to hurt them and "win" the conflict – and if it goes on too long while the other person continues to try to engage, it can make them feel desperate and confused. This is distinct from needing time to cool down and communicate that clearly.
A review by Professor Paul Schrodt of Communication Studies covered 74 relationship studies involving more than 14,000 participants. His findings revealed that the silent treatment is "the most common pattern of conflict in marriage or any committed, established romantic relationship," and that it "does tremendous damage." Couples who rely on it routinely tend to find the original disagreement never actually gets resolved – it just festers.
3. Keeping Score

Scorekeeping is one of those behaviors that often runs quietly in the background for years before a couple even names it. It's the mental ledger of who did what, who forgot what, and who "owes" the other one. Over time, that ledger replaces goodwill with resentment, turning small oversights into evidence of larger failures. Relational factors associated with relationship breakdown include frequent conflict and commitment and trust issues – and scorekeeping quietly fuels all three.
The deeper issue is that scorekeeping prevents genuine repair. Instead of voicing a concern directly, one partner stores it away and responds later in passive, indirect ways. Research from 2024 reveals that individuals in conflict-ridden relationships are at a higher risk of developing mental health disorders such as depression, anxiety, and PTSD. The running tally rarely leads to fairness – it leads to a relationship that starts to feel more like a competition than a partnership.
4. Bringing Up Old Arguments

There's a particular kind of exhaustion that comes from relitigating the same fight from two years ago during an unrelated disagreement today. Couples call it "kitchen-sinking" – piling in every past grievance when tensions rise. It signals that old wounds were never fully processed, and it makes present conflicts almost impossible to resolve. The most effective coping mechanisms in long-term couples include effective communication, drawing closer, and prioritizing the relationship – none of which can happen when every argument becomes a tour of past failures.
What makes this habit particularly draining is that neither partner feels heard. The person bringing up the past feels their pain was never acknowledged. The person on the receiving end feels ambushed. Effective communication is the cornerstone of healthy relationships, with open, honest, and empathetic communication strengthening bonds and improving mental well-being. Letting past conflicts stay in the past – or genuinely resolving them so they no longer resurface – is one of the cleaner ways couples protect their day-to-day peace.
5. Constant Criticism Instead of Specific Complaints

There's a meaningful difference between saying "you always leave dishes in the sink" and "you never care about anyone but yourself." One addresses a behavior. The other attacks a character. Criticism in the second form – sweeping, global, aimed at who a person is rather than what they did – is one of the most reliably destructive patterns in relationship research. Researchers have found that how partners deal with conflict has major implications for the longevity of their relationship, with leading couples researcher John Gottman identifying four specific behaviors that spell serious trouble for relationships.
High-conflict relationships and marriages can lead to increased stress and significant mental health problems for both partners. Criticism that's repeated and character-focused tends to trigger defensiveness, which then blocks any actual problem-solving. Most couples already know what they want to change in each other – the issue is how they ask for it. Shifting from critique to a specific, actionable request is harder than it sounds, but the difference it makes in daily tone is significant.
6. Phone Snubbing (Phubbing)

Phubbing – the practice of ignoring a partner in favor of a smartphone – has become one of the most studied and complained-about behaviors in modern relationships. Research shows that phubbing negatively affects several relational outcomes, including relationship satisfaction, marital satisfaction, romantic relationship quality, intimacy, responsiveness, and overall emotional closeness, while also contributing to increased conflict and heightened feelings of jealousy within relationships.
The experience of being phubbed may elicit emotional rejection, activating attachment-related fears and increasing feelings of jealousy and vulnerability. Intimacy quality is eroded as digital distractions interfere with meaningful connection and attentiveness, with frequent interruptions due to smartphone use diminishing emotional closeness and perceived partner availability. Couples consistently report it as one of the most dismissive feelings in everyday life – not because phones are inherently bad, but because reaching for one in the middle of a real moment sends a clear message about priorities.
7. Social Media Jealousy and Online Surveillance

Social media is a breeding ground for jealousy. It could be a new follower liking a partner's profile pic, an ambiguous comment under a post, or a single emoji taken out of context – and in the long run, jealousy sparked by a partner's online activity can undermine the relationship. What makes this particularly tricky is that the content triggering the jealousy is often stripped of context entirely.
Research demonstrates that social media use plays a meaningful role in shaping young adults' romantic relationships, with social media jealousy at a given time being negatively associated with relationship satisfaction a year later, over and above the well-established contribution of attachment anxiety. This suggests that social-media-related jealousy may stem less from individual personality traits and more from the online environment itself, which peppers users with out-of-context information. The stress this generates – checking, interpreting, worrying – rarely brings couples closer.
8. Avoiding Difficult Conversations Entirely

Conflict avoidance feels like keeping the peace. In practice, it tends to mean that real issues go unaddressed until they become too large to ignore. Couples who consistently sidestep uncomfortable topics often find those same topics exploding into far bigger arguments later, precisely because they were left to grow quietly in the background. Research suggests that stress can drive a wedge into romantic relationships, but understanding how this happens may help couples find a way back together.
Researchers who surveyed over 100 couples found that external stress – including financial problems and unresolved tensions – bled over into relationships, with the more daily hassles participants experienced, the more stress they had in their relationship and the less satisfied they felt with it. Avoiding hard conversations doesn't eliminate the underlying tension. It just delays it – often until the emotional cost is much higher than if the issue had been raised early and directly.
9. Contempt and Eye-Rolling

Of all the behaviors that relationship researchers have documented, contempt is the one most consistently linked to serious relational damage. It goes beyond frustration or criticism. Contempt communicates superiority – a sense that one partner is fundamentally beneath the other. Eye-rolling, mockery, sarcasm used as a put-down, and dismissive sighs all fall into this category. Despite a relationship's potential benefits, all couples experience stress that can increase morbidity and mortality risks, with marital stress altering endocrine, cardiovascular, and immune function – key pathways from troubled relationships to poor health.
What makes contempt so damaging is that it signals a fundamental loss of respect. Despite any health benefits a relationship provides, stress takes a toll on couples' health, with some couples navigating life's inevitable ups and downs while stress erodes others. Couples who allow contempt to become a habitual communication style tend to find it very difficult to reverse, because it rewires how each person fundamentally sees the other. Once you start seeing your partner as someone to mock rather than someone to understand, the whole dynamic shifts.
10. Unequal Division of Labor Without Discussion

Behavioral issues contributing to relationship breakdown include conflict over the division of labor – and this is one area where resentment can accumulate for years before it's ever named. One partner quietly takes on more while the other either doesn't notice or doesn't ask. Neither person has an honest conversation about it. The imbalance grows, and so does the frustration. Types of relationship stressors include stress at the workplace, financial stress, and stress related to children – all of which can spill over into the couple's dynamic and trigger conflict.
The stress here often isn't just about the tasks themselves – it's about feeling unseen and undervalued. When one partner consistently carries more of the invisible load and that reality is never acknowledged or redistributed, it tends to bleed into other areas of the relationship. Research consistently shows that perceived fairness, more than the actual distribution of tasks, is what shapes how satisfied partners feel about their domestic arrangement.
11. Financial Secrecy and Money Fights

Financial worry – the negative thoughts and feelings people carry about money – is closely associated with how partners perceive each other's relationship behaviors. When one or both partners hide spending, avoid financial conversations, or secretly accumulate debt, the concealment itself becomes a trust issue that sits underneath all other conflicts. An awareness that financial worries tend to co-occur with a negatively biased perception of relationship behaviors might benefit couples by encouraging a critical view of their perception of their own and their partner's behaviors.
Money fights are rarely just about money. They tend to be about values, priorities, control, and security – and when those things go unaddressed, they fester. Research shows that actual income or even income regularity is often not associated with perceived relationship behaviors. It's the subjective weight of financial worry that shapes how partners treat each other, not the number on their bank statement. Couples who learn to talk about money with transparency rather than avoidance or blame tend to carry significantly less ambient stress.
12. Excessive Jealousy and Possessiveness

There's a difference between feeling jealous and exhibiting unhealthy jealous behaviors. Normal jealousy is a pang that comes on in an instant, one which most people can dismiss on their own – but unhealthy jealous behavior happens when someone indulges that feeling and acts impulsively from a place of suspicion and insecurity. Over time, that acting-out takes a serious toll on both partners.
When insecurity in a relationship runs rampant, jealousy can rapidly grow into paranoia and obsession and threaten to destroy the very relationship the person is most afraid to lose. People in happy, committed relationships understand that love requires letting their significant other have space to be their own person – they let go of the need to mark territory or scare off competition because they trust each other. Possessiveness often masquerades as love, but couples who look back on it honestly tend to describe it as one of the most exhausting and corrosive patterns they ever experienced.
What makes this list useful isn't the catalog of problems – it's the underlying theme they share. Nearly every behavior on it involves some form of avoidance: avoiding vulnerability, avoiding honest conversation, or avoiding the discomfort of admitting what you actually need. Establishing and maintaining healthy boundaries is essential for mental health, helping individuals protect their emotional well-being and prevent relationship stress. The behaviors that drain couples most are usually the ones standing in the way of something simpler and more direct.
