No, it's not true and Ianto knows as much, because he knows John enough to understand him as far as that. How damned self-sacrificing he is, and how to how far an extreme he would go for that matter.

John at least does have a point. He's putting words into his mouth, and he does know how the other man feels about that. But John still hasn't filled in the gaps himself. Hasn't done much talking at all, beyond demanding of Ianto what it is that he wants of this, and left to his own devices? Ianto isn't the most positive of men. Certainly not at a time like this.

"I'm listening," he says softly. Glancing back up at the other man, his blue eyes dark, guarded, and... Sad. He feels a little as though he's still waiting for the blow to come. That moment when John decides he can't forgive him for this after all. The moment when he realizes he isn't worth it, in the end. Hell, he'd left to give the other man some space, and he couldn't even get that right.
