Well, we'll just have to agree to disagree, because I do not agree that it's a "fact" that the girls aren't trying to get the boys to marry them.
I think the source of the disagreement lies in our definition of "trying to get", but if anything bores me more than Austen, it's arguing with an Austen fan about the exact definition of "trying to get", so I'm going to politely bow out now.
