I like this partly for excellent characters, good plot, partly because h figures out what she needs to do and does it. It takes her a while to realize she can't play monkey in the middle with her feuding parents, cannot be her mom's support/crutch, must be more honest with H. He notes that she never lies but believes she lets him fool himself, is misleading, actually not so.
She finally sees through the OM as a spoiled brat who wants groupies, not a man who will ever want her for herself. She doesn't believe H loves her. He never says so and lets her alone physically and she's very mixed up. H would have been better off to have the occasional touching and kissing, even if it needed to be without passion, because otherwise poor h is left hanging. She's in a MOC that she doesn't want to be in and doesn't know how to get out of it, change it to a real marriage.
H finally gets fed up when he sees OM kiss her and does not see her push him away and tell him off, forcibly seduces her, still doesn’t break through.
