He was married to your mother. You were his adult step-child. This was wrong, but Bruce couldn’t help but be interested in you. You guys weren’t even close. He wanted to talk to you, to learn more, but he felt guilty as hell. He was married and this was entirely inappropriate. He made a vow. He paused leaning against the doorway of your room trying to find something -anything- to talk to you about, he tried to steel his eyes from lingering on your figure, he was Batman for fucks sake. He had years of training and discipline, he didn’t need to be eyeing a person around ten years his senior as a married man.
