First, like so many women my age – I was 45 when I had my affair – I am a supremely talented multi-tasker, unlike my husband, Matt, who quails if you ask him to do more than one job at a time.
Each time Matt and I celebrated another arrival, our sex life would hit the snooze button for a year or so, but then things would be back to normal.
Survey after survey shows that around one in two women will have an affair during the course of a marriage.
For when my head was turned by a hot, younger colleague at work and we embarked on a scorching three-month affair – driven entirely by sexual desire, not love – my husband didn’t have a clue.
I vividly remember us packing up our things from our tiny rented flat and wrapping up Matt’s first gift to me, a ‘world’s best girlfriend’ mug in bubble wrap.
