Artemis: Look, I’ll tell you something else. I mean, Batman is a text-book, closed-off, alpha male. You can try forever, but you’re never going to get that hug that you really want.
Red Hood: Uh, excuse me, I’m not a child. I’m a grown man.
Red Hood’s Brain: And I’ll get that hug!
As closed-off as he seems, Bruce loves hugging his kids (yes, ‘tis canon). And Jason has gotten and does get his share, even in adulthood. It’s just that they both tend to act as if it’s not a thing they long for from each other.
