His words send a tingle down my spine, although I’m not sure what’s part of the act and what’s real any more. I mean, we were pretending to be a couple, then we slept together. Twice. And no one was watching (I hope) so it’s not as if we were pretending then… And now we’re in couples’ therapy, talking as if we’re an old married couple, airing problems that are barely hours old, and not actually real problems.

‘I really care about you too,’ I tell him, just in case he meant it. ‘I think I was more upset about you using our safe word, than you trying to kill me.’

‘I didn’t use our safe word,’ he insists.

‘You have a safe word?’ Victoria asks.

‘We do,’ I tell her. ‘It’s “babe” and he said it to me earlier.’

I don’t waste time explaining.

Freddie laughs awkwardly.

‘I, erm, I wasn’t using our safe word,’ he says. ‘I… I guess I was just calling you babe.’

‘Oh,’ I reply.

‘This all sounds very complex… but your relationship can be as easy as you want it to be,’ Victoria points out.

I suppose that’s a very good way of looking at it. If you just love and respect each other, then what can possibly go wrong? But if you lie and cheat then you’re going to break someone’s heart, give them lifelong trust issues, and completely wreck the infrastructure of your relationship – and without that it will just fall apart.

‘What will happen to the other couple?’ I ask, referring to Jen and Kevin. ‘The, erm, the made-up one you used in your example.’

‘That is up to them,’ Arnold says. ‘Perhaps they’ll realise just how much they mean to each other, stop getting upset over the little things, stop focusing on the road less travelled… or perhaps they are too far gone now. No one can fix a relationship they are not a part of, and no one part of the relationship can fix it alone. Relationships are work. Are you two prepared to put in the hard work?’

‘Our relationship this week has been a series of challenges,’ Freddie says. ‘Quite literally too, taking part in Mr & Mrs Valentine Island. But it all seems worth it. It’s seemed worth it since day one.’

‘When was day one?’ Victoria asks out of interest.

‘Last week,’ Freddie and I reply at the exact same moment.

Finally discharged from therapy, and with a clean bill of mental health to take part in the final round of Mr & Mrs Valentine Island, I actually feel as if I’ve learned something.

Freddie and I might not be a real couple, but all the advice Victoria and Arnold gave us is solid advice. They’re right, about making relationships work, and how it takes effort from both sides. I'm not sure it was the spirit of the conversation, but it does make me wonder whether I was giving Daniel enough – surely that’s a preferable notion, that he cheated on me because I wasn’t giving him enough attention, rather than because he thought Eva was better than I was or because he simply loved her more.
