No, no I haven't? What does it mean? I haven't what?

Context:

Room by room, I saw the traps he'd set for other people, I guessed I was being mocked for having ended up as such a callow failure, trapped in a nothing job. I had no doubt Guy had hacked into everything, collected his data.
I tiptoed round the totems, got more and more freaked out. And then, I found another room, another speaking thing, this time a "woman" – I realised, with a jolt, it was Eloise.
She had long black hair, kohled eyes, she was astonishingly beautiful. I remembered, of course. I had been...
Oh well, I had been...
In love.
"Eloise" was speaking quietly, she always spoke quietly, I had to lean towards her – it.
"Guy, I mean, this is ridiculous. It can't go on. No, no I haven't, are you filming? But just for once... can you stop filming every conversation we have? OK, you've stopped. Yes? Promise. Just this once. Please?"
Her expression was pained, contemptuous, loving – she was in agony. I thought of Guy – past – surreptitiously filming anyway, even when she'd begged him not to.
"We can't go on. I love you but it's too much. I can't do it anymore." She was crying now, the kohl was going everywhere. "No, it's not Doug. I don't even care about him. You know that, surely?"
