A cross-cultural study of married and engaged adults found that having children, but not the number of children, was linked to lower romantic love. This association appeared in intimacy and passion, but not commitment. For marriage-minded adults, that distinction matters when choosing a partner.
The research does not say children damage a marriage. It says the transition to parenthood often arrives with stress, fatigue, money worries and competing demands. Knowing this can help couples plan rather than drift. The findings below come from three recent studies on love, stress and marriage.
What Does Research Say About Romantic Love and Children?
Żelaźniewicz and colleagues (2025) surveyed married or engaged people across 25 countries. The sample included more than three thousand adults, from young adults to people in their nineties. A little over half were women. The study used Sternberg’s triangular theory, which divides love into passion, intimacy and commitment.
Parents reported lower overall romantic love than non-parents. The gap appeared in intimacy and passion, but not in commitment. Notably, the number of children did not change the pattern. One child or several, the link looked similar.
The authors suggest several everyday explanations. New parents face stress, lost sleep, financial strain and work-life conflict. These pressures can crowd out the private time that passion and intimacy need. The study shows an association, not proof that children cause the decline.
The authors recommend that couples actively support their romantic relationship during the parenting years. That advice is practical, not pessimistic. It treats love as something to protect, especially during busy seasons. For singles choosing a partner, it raises a useful question about shared effort.
How Does Stress Affect Marriage and Romantic Love?
Frye-Cox and Yorgason (2026) asked 155 married couples to complete short surveys every day for a week. The researchers looked at stress, loneliness and marital satisfaction together. Both steady and day-to-day loneliness mattered.
For husbands, loneliness changed the stress-satisfaction link. On days when loneliness rose, stress was tied more strongly to lower marital satisfaction. For wives, the pattern depended on average loneliness. Among less lonely wives, higher stress went with lower satisfaction.
Among wives who were lonelier on average, that link was not statistically significant. Loneliness may alter how spouses experience strain. The study design cannot show that one causes the other. It does suggest that stress and loneliness are best read together.
A third study adds texture from a different angle. Ade-Oshifogun and colleagues (2025) interviewed Nigerian immigrants in the United States and Canada. Ten themes of marital dissatisfaction emerged. These included financial stress, job insecurity, extended-family obligations, parenting conflicts and immigration stress.
The sample was small and covered one immigrant group, so it illustrates rather than proves. Still, the themes overlap with the pressures named in the 25-country study. Money, work, family duty and parenting all press on the couple bond. A partner who shares the load is worth looking for.
What Should Couples Discuss Before Having Children?
Talk about time before you talk about logistics. Ask how you will protect private moments once a child arrives. Passion and intimacy need room, and room must be scheduled. Decide what weekly or daily rituals you will keep.
Discuss money openly and early. Financial strain appears as a possible explanation in the cross-cultural study and as a theme in the interviews. Agree on spending, saving and childcare costs before the pressure arrives. A budget is a love document when it prevents resentment.
Name your support network. Extended-family obligations can help or strain a marriage. Decide together what you will accept and what you will decline. Boundaries protect the couple, not just the child.
Finally, talk about loneliness. Daily loneliness changed how stress related to satisfaction in the diary study. Ask each other how you will stay connected during exhausting seasons. A partner who notices your loneliness is a partner who can help carry it.
Professional experience: what relationship advisers observe
Premarital education programs usually cover expectations, money, family roles, conflict style and intimacy. The goal is not to predict the future. It is to practice talking about hard things while the cost of a mistake is still low.
Advisers use these topics as starting points for conversation, not as a pass-or-fail test. A couple that asks these questions early has time to see how the other person cooperates before real pressure arrives.
Lasting change tends to come from repeated practice rather than one deep conversation. Small, consistent habits matter more than a single perfect talk.
Frequently asked questions about children and romantic love
Does having children lower romantic love?
The cross-cultural study found an association, not proof of cause. Parents reported lower intimacy and passion than non-parents. Commitment stayed similar. Stress, fatigue and financial strain may explain part of the pattern.
Does the number of children matter?
In the 25-country study, the number of children was not related to romantic love. Having children at all showed the link. One child or several made little difference. This suggests the transition into parenthood matters more than family size.
Why does loneliness matter for marriage?
The daily diary study found loneliness changed how stress related to marital satisfaction. For husbands, lonelier days strengthened the negative link. For wives, average loneliness shaped the pattern. Feeling alone can make ordinary stress feel heavier.
Can couples prepare for the parenting years?
Yes, preparation is practical. Discuss time, money, family obligations and division of labor before children arrive. Keep rituals that protect intimacy and watch for loneliness in each other. The authors of the cross-cultural study recommend supporting the couple relationship during parenting.
Choosing a Partner With Your Eyes Open
These studies do not argue against children or marriage. They show that love needs care during busy, stressful seasons. The strongest choice may be a partner who talks openly and shares the load. That kind of clarity is worth seeking before you commit.
