His Rules

It's not that he didn't have any rules, in fact he had many rules. Perhaps he had too many rules, she first felt. But she came to discover that he broke the rules he had, or the rules he said he had. Or he said he had a rule, but he didn't say (at first) that he hadn't always had that rule, that he had done certain things before that were against that rule but later (perhaps as a result of doing those things) he made a rule to not do them. Or he did always have that rule, but he did not always stick to that rule, though he wished he would always stick to that rule in the future. So when he said he had rules, he listed those rules, which he wished he followed, which he wished he was the kind to follow, the kind to have always followed.
