Trouble is, I love her. I want her to be happy because she’s made me happy, and Leo adores her. After Zoë died last year, the guilt was overwhelming, but Liv made me see that in the end, Zoë made choices that no one else could have changed . . .

And that Leo needed me to keep it together even more than before.

‘You know it’s not that simple for me, Liv.’

‘Well, here’s simple. We’ve been together a year, which is enough time to know one way or another. Meanwhile, I want a child, and I’m thirty-five and if you don’t want one too, I probably need to look for someone who does.’ Her voice is calm, but as she turns to leave the flat, I see her face is flushed with frustration.

I should tell her to wait, so we can talk it through some more. Except where do we go from here? This isn’t about me wanting a beach holiday and Liv wanting a city break. We’ve had exactly that scenario already and ended up in Stockholm, because she talked me round, as she generally does.

I open the folding doors again and look over the terrace, watching her stomp away down Gardner Street, before she disappears. She’ll be heading for the sea, where she’ll drink a double espresso in her favourite cafe, curse me under her breath, skim a few stones with frightening accuracy and head back feeling calmer . . .

Could we try counselling? There aren’t many counsellors who’d be a match for Liv’s bossiness. Ant sometimes tells me I’m hen-pecked. I prefer directed: Liv and I work together quite often, so it’s natural that she falls into calling the shots at home as well as on location. But despite the teasing, Ant thinks it’d be grounding for me to have another kid. And his little girls love babies.

It’s so seductive, the idea of doing an even better job this time: being there when Liv does the pregnancy test, for the scans and the shopping and decorating the nursery. Our penthouse has a lift for a pushchair and the terrace for shaded naps on warm summer days, or we could always sell it to move to Hove.

I can picture Liv cocooned in the hanging chair in front of me, feeding our baby – a girl, I think – with Leo proud to be a big brother.
