Yes, it was Robbin who mentioned that in her post Observations & Misconceptions. I missed it too, I think because the conference is so mortifying, by the end of it we've forgotten what Henry might have said.

I know he spoke to you yesterday, and (as far as I understand) received as much encouragement to proceed...

Fanny said ...How could Mr. Crawford say such a thing? I gave him no encouragement yesterday...I cannot recollect my exact words, but I am sure I told him that I would not listen to him, that it was very unpleasant to me in every respect, and that I begged him never to talk to me in that manner again.

So I went back to Mr. Crawford's proposal and indeed it was just as Fanny said.
“Don’t, Mr. Crawford, pray don’t! I beg you would not. This is a sort of talking which is very unpleasant to me. I must go away. I cannot bear it"
She said that before she understood it was a proposal.
...finally, in words so plain as to bear but one meaning even to her, offering himself, hand, fortune, everything, to her acceptance. It was so; he had said it....
“No, no, no!” she cried, hiding her face. “This is all nonsense. Do not distress me. I can hear no more of this. Your kindness to William makes me more obliged to you than words can express; but I do not want, I cannot bear, I must not listen to such—No, no, don’t think of me. But you are not thinking of me. I know it is all nothing.”

And yet Henry thinks...when her modesty alone seemed, to his sanguine and preassured mind, to stand in the way of the happiness he sought.

At first I thought, that Henry must have outright lied to Sir Thomas, but then reading this... If he really took all those negative things she said as just modesty, it seems he is stupid and Mr. Collins-ish.

You know what gets me is how all of the men around Fanny take her gentle manner to mean the opposite of what her words say. I was going to talk about this in a future chapter, but I realize now there is enough here.

“If it were possible for me to do otherwise” said she, with another strong effort; “but I am so perfectly convinced that I could never make him happy, and that I should be miserable myself.”

Another burst of tears; but in spite of that burst, and in spite of that great black word miserable, which served to introduce it, Sir Thomas began to think a little relenting, a little change of inclination, might have something to do with it;

So in spite of her repeatedly saying no and the miserable, I wonder if they are taking those bolded phrases she said as encouraging. Ack!

Back in Ch. 25 when Sir Thomas realizes Mr. Crawford is distinguishing his niece, and Fanny’s reception of it was so proper and modest, so calm and uninviting, that he had nothing to censure in her. She said little, assented only here and there, and betrayed no inclination either of appropriating any part of the compliment to herself, or of strengthening his views in favour of Northamptonshire.

You know, if she had any inclination towards Mr. Crawford, it should show somewhere. Perhaps Sir Thomas should realize that an uninviting manner means she couldn't care less about the dude!

I sense more chauvinistic attitudes in there, that they think that Fanny doesn't mean what she says. No means NO! Geez.
