Of course she knew well enough that marriage was not always the blissful transformation it had been for her. There were unhappy marriages. There were such things in the world as unfaithful husbands and brutal drunken husbands, who had to be divorced. And equally, too, there were cold-blooded, designing, mercenary wives. (In the back of her mind was the unacknowledged notion that these people existed generally in novels. She knew, of course, that those characters must have real prototypes somewhere. Only, it hadn't occurred to her to identify them with people of her own acquaintance.) But the idea had been that, barring these tragic and disastrous types, marriage was a state whose happy satisfactoriness could, more or less, be taken for granted. Oh, there were bumps and bruises, of course. She hadn't forgotten that tragic hour in the canoe last summer. There had, indeed, been two or three minor variants on the same theme since. She had seen Rodney drop off now and again into a scowling abstraction, during which it was so evident he didn't want to talk to her, or even be reminded that she was about, that she had gone away flushed and wondering, and needing an effort to hold back the tears. These weren't frequent occurrences, though. Once settled into what apparently was going to be their winter's routine, they had so little time alone together that these moments, when they came, had almost the tension of those that unmarried lovers enjoy. They were something to look forward to and make the delicious utmost of. So, until she got to wondering about Bertie, Rose's instinctive attitude toward the group of young to middle-aged married people into which her own marriage had introduced her, was founded on the assumption that, allowing for occasional exceptions, the husbands and wives felt toward each other as she and Rodney did--were held together by the same irresistible, unanalyzable attraction, could remember severally, their vivid intoxicating hours, just as she remembered the hour when Rodney had told her the story and the philosophy of his life. Bertie, or rather the demand for what Bertie supplied, together with Frederica's explanation of it, brought her the misgiving that marriage was not, perhaps, even between people who loved each other,--between husbands who were not "unfaithful" and wives who were not "mercenary"--quite so simple as it seemed. The misgiving was not very serious at first--half amused, and wholly academic, because she hadn't, as yet, the remotest notion that the thing concerned, or ever could concern, herself; but the point was, it formed a nucleus, and the property of a nucleus is that it has the power of attracting to itself particles out of the surrounding nebulous vapor. It grows as it attracts, and it attracts more strongly as it grows.
