On the plus side: Marianne has figured out that she's been a mopey whiner.
On the minus side: Instead of trying to buck up and behave better, she's added self-flagellation to her bag of tricks.
First, she meets with Miss (Nancy) Steele in the park and has to hear all the details that (it turns out) Miss Steele learned while eavesdropping through a keyhole - Edward stayed away from Lucy for three days, then turned up to offer her the opportunity to call their engagement off, given his change in circumstances.
Next, she gets a letter from Lucy Steele, telling her that Lucy offered to let Edward off the hook and he wouldn't hear of it. (Cue Miracle Max's wife hollering "LIAR! LI-AR!!")
Edward is up a creek
His mother has disinherited him. His annual income is the interest on 2,000 pounds, which is not a whole lot of money to live on. On the plus side: He is going to be a minister after all - he said early in the book that if he had his way, he'd enter the clergy, and now it's pretty much going to be a necessity. On the minus side: His mother has said she'll do what she can to thwart any profession he seeks, so it seems likely he'll be stuck with a curacy, which isn't even a permanent position. A vicarage was a life estate in a particular parish, but a curacy meant that someone else was actually possessed of the living, but they didn't live there - instead they allowed another cleric to live at the parish and perform the job functions, but for much less money than they'd have gotten if they'd held the actual living. Further on the minus side: Edward is still saddled with Lucy Steele, whom he still doesn't love. This is a downside for Edward as well as for Elinor.
