1. ] I have not suggested that Elizabeth cares the least bit for a Charles Musgrove or a Frederick Wentworth

I didn't say you have. ;)

And the opinion I posted earlier is still exactly the opposite of what you now propose ("that she cares about being passed over and is therefore jealous of Anne who has not"). As I said, imo, Charles and Frederick are too inconsequential enough that I think Elizabeth wasn't at all bothered about whatever decisions they did in life. If they wanted to marry Anne, fine. If they preferred Mary, whatever. Something like, if she wasn't proposed to by these kinds of men, then, blah, she didn't miss anything. The way I see she perceives her worth, I don't think she takes it against Anne or Mary that those inferior, unconnected men admired them. She has bigger fish to fry, so to speak.

2. Yes, she was disappointed with the way things turned out with Mr. Elliot. But (and here is the teeny textual evidence I couldn't say yesterday), we now learn that "the men are all wild after Miss Elliot". Hence, we know for a fact that she is greatly admired by men in Bath. It will not be too much of a stretch to think that some men have previously admired her even before. Or that some did and do consider asking for her hand. (Pff. Idiots!)
