He was there for your use. If you were hungry, you'd seek him for his blood. That's all you wanted him for, his blood...or so he thought. There was nothing more between you and him, right?

You made sure to drink from him in considerate amounts, enough so that it left you sated and him in a blissed out puddle. You knew the affect you had on him and he never once objected against your feedings.

You couldn't deny him, not when he came to you, baring his neck as an invitation for a feeding. He knew you were hungry even when you hadn't told him.
