Hey now, she'd been into her childhood friend well before that!
Which is probably part of the problem: he does care for her, but as his childhood friend or like a (normal) sister. It's a pity marriage without romantic spark.
The issue is not the longevity of Kaoru's feelings, the issue is: what does Reiichi have going for him that makes him so great to this particular person?
Now, I know that love doesn't work by a cost/benefit equation; you fall in love with who you fall in love with.
But this is a story with the theme of romantic attraction at the center of it (whether you want to characterize its genre as "romance" or not).
And the very reasonable question of why exactly Kaoru feels so strongly about Reiichi (who is at best--which means putting the whole issue of possible infidelity completely aside--a pretty drab, ordinary, low-charisma guy who pays little attention to Kaoru's emotional state), has been explicitly asked within the text itself, but has yet to be answered.
