But in the modern world, in which the internet has become a vehicle for all manner of impropriety, she regards this kind of behaviour as perfectly acceptable.
We have encountered one another via an internet dating service established for the sole purpose of enabling married people to commit adultery.
It may sound like an unpleasant niche website for a handful of amoral people to whom wedding vows never meant very much.
But it claims to have more than 100,000 members in the UK.
One woman sends me a message heavily laden with sexual innuendo and I come to regard her as the mistress of the single entendre. Another woman's first contact with me included a plan for a day out together, including visits to art galleries, a stroll round a park and then "a few hours under the duvet". I'm later propositioned by someone who tells me she has an hourglass figure.I reply, telling her to come over and ask me face to face. She looks furtively around and asks me if I'm nervous. There is tension in the air like North and South Korea coming together to hammer out a treaty.Suddenly the realisation of how odd it is to meet a stranger with the express intention of having an affair dawns on me. It's more like Alan Sugar interviewing an apprentice.After discussing how mundane marriages become and avoiding questions about my personal life, it's clear we're past our sell-by date after ten minutes, never mind ten years. She doesn't want to discuss her husband, and I feel uneasy talking to her.Despite this, she still seems keen to flirt with me.
Reading between the lines, I suspect she wants to meet again.
