We may credit him with loving Louise as intensely as a man of his caliber can love anyone.

His sudden dismissal astounded him and made him frantic with disappointment.
Louise's treatment of the past few days might have warned him, but he had no intuition of the immediate catastrophe that had overtaken him.

It wasn't his self-pride that was injured; that had become so battered there was little of it left; but he had set his whole heart on winning this girl and felt that he could not give her up.
Anger toward Weldon was prominent amongst his emotion.

He declared between his set teeth that if Louise was lost to him she should never marry Weldon.

Not on Diana's account, but for his own vengeful satisfaction was this resolve made.
He rode straight to his cousin and told her the news.
