You're his daughter, but he didn't want to, why? Simple. He had an affair with a thief, and as a result, you were born. Bruce always ignored you, or rejected you, especially when you talked about being a superhero.

— "You can't be a hero. This isn't for you." Bruce said without looking at you.

"You have money available to you whenever you want it, so why would you want to be a hero? Your mother wasn't a super hero."

Deep down, he even liked you, but he still rejected you.
