1. Letting contempt slip into everyday conversation
Contempt looks like eye-rolling, sarcasm, mocking tone, or a sigh that says more than words ever could. Contempt is the most destructive of the four horsemen, and Gottman’s research identifies it as the single greatest predictor of divorce. It’s not the shouting matches that do the most damage, it’s the quiet sneer during a disagreement about dishes or money.
What makes contempt so frightening is how normal it can start to feel. It shows up as sarcasm, mockery, eye-rolling, sneering, hostile humor, and name-calling. Once a couple starts talking to each other that way regularly, the relationship has usually already started to erode long before anyone brings up the word divorce.
2. Criticizing instead of requesting
There’s a real difference between saying “you never help around here” and asking for specific help with something tonight. The first is an attack on character, the second is a request. Criticism opens the door, and when criticism becomes habitual, contempt follows.
Many women say this is the habit they catch themselves doing most, often without meaning to. It usually starts small, a passing comment about a partner’s laziness or forgetfulness, and it can feel justified in the heat of frustration. Over time, though, it teaches a partner to expect blame rather than partnership, which chips away at the sense of being a team.
3. Shutting down and going silent during conflict
Stonewalling is when one partner simply checks out mentally during an argument, refusing to engage, sometimes physically leaving the room. Contempt invites defensiveness, and when defensiveness fails to resolve anything, stonewalling takes over, creating a loop where each partner’s worst response triggers the other’s worst response and the space for repair shrinks with every cycle. It’s a habit that often starts as self-protection but ends up feeling like abandonment to the other person.
Women frequently describe this as one of the loneliest experiences in a marriage, worse in some ways than open conflict. At least a fight means someone’s still trying. Silence, especially the kind that lasts for hours or days, can quietly convince a partner that the relationship isn’t worth fighting for anymore.
4. Keeping financial secrets, even small ones
Hiding a purchase, a credit card, or a stash of savings might feel like a private matter, but it rarely stays that way. A Bankrate study found that two in five people in a committed relationship have committed financial infidelity. The most common form isn’t a hidden bank account, it’s simply spending more than a partner would be okay with, followed by things like secret debt, secret bank accounts, or secret credit cards.
What makes this habit so damaging is that it’s rarely about the money itself. It’s about the secrecy, and secrecy tends to breed more secrecy once it starts. Financial infidelity also appears to be generational, with a big jump in financial infidelity among younger people, which suggests it’s becoming more common rather than less.
5. Refusing to take responsibility for mistakes
Defensiveness sounds like constant excuses, deflecting blame back onto a partner, or treating every piece of feedback as an attack. It’s a natural instinct when someone feels criticized, but it stops real conversation in its tracks. Instead of hearing “I felt hurt when you forgot,” a defensive partner hears “you’re a bad person” and responds accordingly, even if that was never the intended message.
The frightening part for many women isn’t the disagreement itself, it’s watching a partner consistently avoid owning anything. Over years, this can create a dynamic where one person feels like they’re always doing the emotional heavy lifting. Eventually, that imbalance becomes exhausting enough to threaten the marriage on its own.
6. Letting phones replace real conversation
It’s an easy habit to fall into: sitting together on the couch, physically present but mentally elsewhere, scrolling instead of talking. Researchers sometimes call this “phubbing,” short for phone snubbing, and couples therapists report seeing it come up constantly in sessions. It’s rarely the phone itself that’s the problem, it’s what the habit signals about where a partner’s attention actually goes when given the choice.
Women often describe feeling like they’re competing with a screen for basic acknowledgment. That feeling, repeated night after night, can start to feel like emotional neglect even when nothing dramatic has happened. Small moments of connection, a shared laugh, a quick check-in about the day, are often the first casualties of this habit.
7. Comparing a partner to others, online or in person
Social media has made comparison almost automatic, whether it’s a friend’s anniversary post or a stranger’s curated relationship highlights. Saying things like “why can’t you be more like” someone else, even as a joke, tends to land as a direct hit rather than harmless teasing. It plants a seed of inadequacy that’s hard to shake, no matter how the comment was intended.
This habit is particularly frightening because it often happens casually, almost without thought. A partner might not even remember making the comment a week later, but the person on the receiving end usually does. Repeated comparisons, however lighthearted they seem, can quietly convince someone they’re falling short in a relationship where they should feel secure.
8. Keeping a mental scoreboard of grievances
Some couples fall into a pattern of tallying who did what last, who forgot the anniversary, who canceled plans, who apologized first. It can feel fair in the moment, a way of balancing the scales. In practice, it usually just stockpiles resentment that gets unloaded all at once during the next disagreement, often over something unrelated.
This habit is dangerous because it turns partnership into competition. Instead of asking “how do we fix this together,” the question becomes “who’s winning.” Marriages built on score-keeping tend to feel more like negotiations than relationships, and that shift rarely goes unnoticed by either person.
9. Letting physical affection quietly disappear
It doesn’t have to be dramatic. No affairs, no big fights, just fewer hugs, fewer hands held, fewer moments of simple physical closeness. Many couples don’t even notice the decline until it’s been going on for months or years, at which point reconnecting can feel awkward rather than natural.
Women often say this is one of the scarier habits precisely because it’s so easy to justify. Busy schedules, kids, exhaustion, it all adds up to reasonable-sounding excuses. But physical affection tends to reinforce emotional closeness, and when it fades for long enough, the emotional distance tends to follow right behind it.
10. Venting about the marriage to everyone except the partner
Talking to friends or family about relationship struggles is normal and often healthy. It becomes a problem when it replaces talking to the actual partner, or when it turns into a running narrative where one spouse is consistently painted as the villain. Over time, this habit can make it harder to see a partner’s side clearly, because the story has already been rehearsed and reinforced by outside voices.
It also creates a strange dynamic where a partner is often the last to hear about problems everyone else already knows about. That can feel like a quiet betrayal, even without any romantic involvement outside the marriage. Women who recognize this pattern in themselves often say it took years to realize how isolating it had become for their spouse.
11. Prioritizing parenting or extended family over the marriage
Kids and in-laws matter, obviously, but some couples slide into a pattern where the marriage itself quietly moves to the bottom of the list. Date nights disappear, private conversations become rare, and the relationship starts running almost entirely on logistics: schedules, chores, and childcare handoffs. It’s a slow shift, and that’s exactly what makes it so easy to miss.
This habit is especially common among women juggling work, kids, and household management, where self-care and couple time get sacrificed first out of necessity. The frightening part isn’t the sacrifice itself, it’s realizing years later that the marriage has become more of a logistical partnership than an emotional one. Rebuilding that closeness later takes real intention, since it rarely comes back on its own.
12. Letting fondness and admiration quietly fade
Every long relationship experiences some wear on the initial spark, that’s expected. What’s riskier is when partners stop noticing or mentioning the things they actually appreciate about each other. The antidote researchers point to for the most corrosive relationship habits is straightforward: building a culture of appreciation and fondness.
When that culture disappears, small irritations start to outweigh the good moments, simply because the good moments are no longer being acknowledged out loud. Women who’ve been through long marriages often describe this as the habit that’s hardest to catch, because nothing bad is technically happening. It’s the absence of something good, and absences are always harder to notice than actions.
