Anyone recognise this book

[Viviennemary]

I read this book a few years ago but not sure if I finished it but would like to. A woman has an affair. I think they were both married but not absolutely sure. It was very genteel and not much passion. But the bit I remember was he owned a flat where they used to meet near a leafy square in London probably.. But after the affair ended the flat was sold but she still used to go and sit on a bench in the square not because she was sad but she hadn't anything better to do. (Sounds awful I know!)

I thought it might be a Barbara Pym or Anita Brookner but still can't trace it at all. Just wondered if it rang a bell with anyone. Thanks.

Sounds like the kind of thing Milan Kundera would write, maybe Life is Elsewhere? I'm struggling to remember which of his novels is which but I'll check in a bit...

It’s not The Last Letter From Your Lover by Jojo Moyes? That has a couple in it who are having an affair and if I remember right they meet in a square. Can’t remember a flat being sold though.

Thanks very much for the replies. I've not heard of Milan Kundera but I think it's a female author. Don't think it's Jojo Moyes either though I have heard of her and might have read a couple of her books.
