Oh god. This made me sick to my stomach... However bitter the situation is, I feel like I should welcome the coming crash like a good masochist.

@Sarsak I wonder why Reiichi doesn't want the marriage to end. Is he still afraid that Kaoru's going to work herself to death in depression?//
Um, I think that's a part of it. But there's a part too, it seems to me, Reiichi will like to save face. Even though he moved out, perhaps he will try to prove her wrong or (since Kaoru figured it out fast and furious) at least allay Kaoru's doubts that he doesn't love her in a romantic/sexual sense.
I think Kaoru's pretty much resolved to ditch the marriage, she just wants to hear Risako's side of the story for closure.
