Quote #4
"Shrimps! Oh, Bobinôt! you too good fo' anything!" and she gave him a smacking kiss on the cheek that resounded, "J'vous réponds, we'll have a feas' to-night! umph-umph!" (3.7)
By praising Bobinôt and "kiss[ing]" him so loudly, Calixta seems to be overcompensating for cheating on him. Look at the number of quotation marks here. In her relief and excitement about his return (and possibly her guilt over what she's done), she's laying it on a bit thick.
Quote #5
Alcée Laballière wrote to his wife, Clarisse, that night. It was a loving letter, full of tender solicitude. He told her not to hurry back, but if she and the babies liked it at Biloxi, to stay a month longer. He was getting on nicely; and though he missed them, he was willing to bear the separation a while longer – realizing that their health and pleasure were the first things to be considered. (4.1)
Just like Calixta in the preceding quote, Alcée seems to be overcompensating for his guilt here. He writes his wife a note that makes no mention of his infidelity. If anything it seems to present him as a noble self-sacrificer, giving up his time with his wife and children for their own good.
Quote #6
And the first free breath since her marriage seemed to restore the pleasant liberty of her maiden days. Devoted as she was to her husband, their intimate conjugal life was something which she was more than willing to forego for a while. (5.1)
Clarisse claims to be "devoted...to her husband" while at the same time explaining that she doesn't mind spending time away from him. You'd expect that if she's so "devoted" she'd be reluctant to stay away longer, or at least have to force herself to put up with it. Instead, she's "more than willing" to take an extended break.
