Aside from the obvious reason, that he's a selfish little prick, I guess it's the loss of what he thought was undying devotion? Maybe he took more comfort in her love than he thought, and her leaving him and marrying another man is brushing his ego.
But I feel like there should be something else wrong with him too? He really goes beyond the usual shitty ex-boyfriend behavior...
Can someone explain the duke for me? Like I thought he doesn’t like her. It doesn’t seem like just guilt or possessiveness, I don’t know why he’s acting that way. He doesn’t like her anyway, why want her back?
