Useful takeaways from this story.

Wealth, nationality, or professions are less important than behaviour: discreet generosity and consistent care matter more than flashy claims.

Set clear standards and be prepared to walk away when a partner’s circumstances or emotional capacity won’t meet them.

Keep relationships that bring value even if they aren’t ‘The One’—some dates become lasting friendships or periodic check-ins.

The useful part

Louise O'Neill on what she learned about dating again at 39 (Image credit: L+R: We had been together for five years and had bought our first home together six months previously. Overnight, the future I assumed I would have-marriage, children -imploded, and I was left to pick up the pieces.

How it works

  • Firstly, I went to Thailand on a yoga and wellness retreat, followed by hours and hours of therapy.
  • French men are obsessed with the Eiffel Tower and will insist on showing it to you.
  • I am now an expert in pickling and the workout regimen of a professional boxer, both entirely against my will.
  • I might have been devastated, but I was also a millennial woman who had read Eat Pray Love at an impressionable age, so I knew what to do next.

What to take from it

Just because they're not The One doesn't mean you can't stay in touch. I went to Paris for June 2024, changing my Hinge location, and over the next 21 days, I went on 28 dates. I repeated this experiment in London, New York and Rome, and I learned so much about myself, but I also learned a lot about men...

Example or evidence

  • Build a life so good that a man has to earn his place there.
  • If you're in his dating range on Hinge, he doesn't care, so you shouldn't either.
  • Some men will make you listen as they recite their poetry to you after you've had sex.

Details worth keeping

When I was about to turn 38, my partner broke up with me. Then I decided to do the most terrifying thing imaginable. It will be about his divorce and will include an analogy about swans that you won't understand.
