Quote #7
What none the less came to him, however, at this hour, was that the society over there, that of which Sarah and Mamie—and, in a more eminent way, Mrs. Newsome herself—were specimens, was essentially a society of women, and that poor Jim wasn't in it. (8.2.12)
Strether feels bad for poor Jim Pocock, although he's not sure why at first. As he spends more time with the man, though, he realizes that Jim has married into a family that's completely dominated by women, and not the type who just wanna have fun. They make the decisions and set the rules, and there's not much for Jim to do apart from what he's told by Sarah. This is the same family fate that Strether needs to avoid by separating himself from Mrs. Newsome.
Quote #8
[Jim] gurgled his joy as they rolled through the happy streets; he declared that his trip was a regular windfall, and that he wasn't there, he was eager to remark, to hang back from anything. (8.2.13)
As you can tell from the word, "gurgle," Jim feels as happy as a baby when he gets in a cab with Strether and realizes that he's going to have some time away from his wife in Paris. Poor Jim is desperate for the same sense of freedom that Strether has felt in this great city, and getting away from Sarah and her mom seems to be the only way of doing it.
Quote #9
'[W]hat is you conduct by an outrage to women like, us? I mean your acting as if there can be a doubt—as between us and such another—of his duty?' (10.3.10)
For Sarah, there should be no doubt about where Chad's duty lies. The fact that he's living an interesting life with people he cares for doesn't matter. She's his flesh and blood and his responsibility is to her and her mother. Besides, the Newsomes have a family business to maintain, and it's Chad's job as the only son to carry on his father's legacy.
