Henry hated what he had done. He hated that he had to send Layla away from him. He hated that he couldn't keep her by his side. He hated that he hadn't been able to protect her.
What he hated the most was that he knew he had also done the right thing. He knew that sending her away from his territory, from his home, had probably been the best way that he could protect her.
Auburn was never going to stop coming for him or coming after him. He wasn't going to stop until he had all of Wolfsbane's territory under Bloodmoon's control. And he was going to do whatever he needed to to make that happen.
That meant Layla was in danger.
Henry had to protect her, above all else, so he had sent her away. Even as he sent her away, a part of him had rallied against himself, trying to stop him from his actions.
He knew that doing anything else would have been a selfish endeavor, plain and simple.
