At the start of the year, we often want to feel better in our lives… and in our relationship. And for some, this period of transition also brings out more unexpected desires. According to the extra-marital dating application Gleeden, this Monday in January is accompanied by a notable increase in activity on the platform.
New year, new resolutions… new temptations?
Get back into sport, stop smoking, eat healthier… and take a lover? If the idea may make you smile, this “good resolution” is in reality taken very seriously by the French.
“Infidelity stands out (…) as one of the great temptations of the new school year”, ensures the site.
Indeed, according to the data collected by Gleeden, the observation is clear: January stands out each year as the most active month on the platform. And at the heart of this peak of activity, the second Monday in January systematically concentrates “the biggest increases in traffic and registrations“, becoming the most risky moment for couples. However, in 2026, this peak falls… on Monday January 12. You have been warned!
“It is at this precise moment that the search for extramarital affairs intensifies the most,” confirm the site’s experts.
Moreover, the figures from recent years speak for themselves:
- On Monday January 10, 2022, activity on the platform recorded a spectacular increase of +490%;
- The phenomenon repeated on Monday January 9, 2023, with +410% activity, before further intensifying on Monday January 15, 2024, reaching +510%;
- In 2025, the trend was confirmed once again, with +530% activity observed on Monday January 13.
January, that moment when the couple falters
If January seems to be the month of seduction, it is because the start of the year is often synonymous with weariness and frustration: the French are confronted with this diffuse feeling.that something is missing“. The return to routine, after several intense weeks on an emotional and family level, then acts as a revelation.
“It is often at this moment that the need for novelty, the lack of attention or desire, and the desire to refocus on oneself resurface. So many signals which explain why this period constitutes a particularly favorable terrain for questioning… and sometimes for deviations”, analyze the Gleeden specialists.
An infidelity that is all the more present among women, who have the feeling of having forgotten themselves for the benefit of others. In this context, January becomes a key moment for them to regain control of their desires, their desire and their individuality.
“Infidelity is not always experienced as a breakup, but rather as an attempt to regain control over one’s emotional life. A way of getting out of a routine that has become burdensome, of allowing oneself to explore desires that have been set aside and of reconnecting with oneself,” concludes Solène Paillet, marketing and communications director of Gleeden.
