How we cite our quotes: (Paragraph)
Quote #4
"Listen, baby," he said, "while you're talking about things like that, why didn't you marry Joe Brooks? I suppose he could have given you all the twenty-two dollar hats you wanted, I suppose!"
"Well, I'm not so sure I'm not sorry I didn't," she said. "There! Joe Brooks wouldn't have waited until he got me all off alone and then sneered at my taste in clothes. Joe Brooks wouldn't ever have hurt my feelings. Joe Brooks has always been fond of me. There!" (56)
Yowch. It's pretty extreme to say you should have married someone else less than three hours after your wedding. But we can't take this that seriously—the wife is still fishing for some comfort, really, some security as to whether she made the right choice. She wants her husband to reassure her about marrying him.
Quote #5
"Listen," he said. "I don't want anything he gives you in our apartment. Anything he gives you, I'll throw right out the window. That's what I think of your friend Joe Brooks. And how do you know where he is and what he's going to do, anyway? Has he been writing to you?" (53)
The husband rises to the wife's bait and argues passionately with her. But maybe this is a good thing (from the wife's perspective)—he's demonstrating that he cares about her and doesn't want her to be corresponding with any dudes who might be interested. It shows he's attached to her.
Quote #6
"I suppose my friends can correspond with me," she said. "I didn't hear there was any law against that."
"Well, I suppose they can't!" he said. "And what do you think of that? I'm not going to have my wife getting a lot of letters from cheap traveling salesmen!" (61-62)
Basically, the comment on the last quote applies here. The husband's passion might (again, from the wife's perspective) be a good thing—it should make her feel more secure, in that she's married someone who cares about her (or, at least, cares enough to be jealous on occasion).
