There was nothing he could do to call the girl back because she caught him, she was right, he had just wanted to use her all along and there was just one woman his heart yearns for which was his wife. His wife had always accused him of cheating so he wanted to cheat so that her assumption would be right. No, he wanted to cheat so he could feel much better. He didn't even know why he wanted to cheat, he had to admit to himself that he was just out of control.
He was upset with his wife and himself and with Kathryn having feelings for him, he decided to use her feelings to get the better of her but the girl being a water demon, she could tell his true feelings. Well, every girl could tell a man's true feelings, some just turn a blind eye to it.
