Lol the guy is 28! If he's still behaving like that, he's a lost cause. Why on earth would she want to win someone like that over? I get that they need that kinda logic for the romance to work but...i realllly doubt anyone would be trying for that in this situation. She married for money and oh boy did she win the lottery there, the husband doesn't even give a shit if the brother is against it so why is she bothering? Hell, even if it eventually leads to divorce she'll be fine, there WILL be money to be made there too.
