"He had intended, on first arriving, to proceed very soon into Shropshire, and visit the brother settled in that county, but the attractions of Uppercross induced him to put this off. There was so much of friendliness, and of flattery, and of every thing most bewitching in his reception there;" (ch 9)

So what does Captain Wentworth believe to be the attractions of Uppercross? He is so well-liked, almost fawned over - that must be an attraction. He is as bewitched with his reception as the Musgroves are with him.

I can't help but wonder if part of the attraction of remaining is to show Anne just how popular he is, how wanted he is, how some people are eager for his company. I'm not saying that he remained just to rub it in Anne's face, but he'd be less than human if he didn't take some satisfaction from it.
