If Paris is the capital of love, it’s no longer the capital of infidelities. According to Gleeden, it’s now Bordeaux that takes the top spot, with 13.26% of its adult population registered on the platform. This growth represents a true shift in the times.
Close behind, Lille (12.94%) is hot on its heels, while Paris rounds out the podium (10.44%). This reversal illustrates the changing practices, but also the profiles: active individuals, often in relationships, with children, belonging to higher socio-professional categories. Far from the cliché of marginal infidelity, these users lead well-established lives where personal aspirations sometimes shake up the balance.

After the health crisis, a new map of desires
To understand this shift, we need to look back to the post-Covid period. The health crisis has profoundly changed life priorities, prompting many French people to leave big cities for more breathable places like Bordeaux, Lille, or Nantes.
With the rise of remote work, these new balances allow for a blend of career and quality of life… without necessarily changing romantic behaviors. Fewer constraints, more flexibility: opportunities for parallel encounters are multiplying.

This phenomenon mainly reveals some contemporary tensions: between family life and the desire for personal growth, between a displayed stability and yearnings for something different. Infidelity then appears less as a break than as an adjustment.
Infidelity Now Everywhere in France
Another key takeaway: infidelity is no longer concentrated in a few major cities. It is now spreading across the entire territory. In the rest of the ranking, we find Lyon (9.60%), Rennes (8.28%), Toulouse (7.77%), and even Nantes (7.27%). These are dynamic, attractive cities where lifestyles tend to homogenize.
