He was blaming you right now, telling you that you were involved in his decisions and that you are a bad influence on him, you can't believe that's happening, it's like listening to a child throwing a tantrum.
He knows that maybe he's not being very fair right now, but he's very angry with himself and with you. None of that would have happened if you had said yes. So it's your fault, not his.
But... He also knows that he acted wrongly even though you encouraged it and now he may have already lost his eldest son and his friend Gordon. Having casual encounters with Barbara was a bad idea, especially doing it without a condom and getting her pregnant, only to be discovered and have a fight with his son, which led to her having an unexpected abortion.
Yes, he had sex with his oldest son's young girlfriend because he was sad and didn't stop her when she kissed him and then got naked. Why was he sad? Because two days before he had asked you out after a long time of hesitating and hesitating, but you said no, that you weren't ready to go out with anyone and that he was an incredible friend. You told him friend that hurt him more than just being rejected with a no, did you have to say that ugly word? He doesn't want to be your friend, he's been in love with you for years and didn't want to hear that just he is a friend to you.
So the first thing he felt was anger and offense, he went back to being serious and building walls around himself. And well, two days later that happened with Barbara, which was repeated for the next three months. He found comfort in her, knowing that she wanted him made him feel good again, not miserable, it made him feel like a man and not just a damn incredible friend He didn't care about Dick or the relationship Barbara had with Dick, he just wanted to feel desired, attractive and powerful, that's why he didn't use a condom.
He didn't expect her to get pregnant, when he found out, well he didn't have time to think about it because Dick heard the conversation and started fighting with him, which led to Barbara getting stressed. And well, there she lost the baby.
Does he feel pain about that? No, not really. He didn't want another baby, much less from her. In fact, he only wants to have babies with you. And one of his secrets is that if that baby had been born, he probably would have named it after you. Good thing Barbara had that abortion.
Now yes, his son doesn't talk to him and neither does Gordon, much less Barbara, he is not surprised he expected it, what he didn't expect was you, you entered the Batcave, he was checking something and saw you walking towards him.
You expressed your anger because you found out what he did and went to reprimand him but at first he only focused on how your scarlet-red hero suit was squeezing your body. It looked so good on you, he could literally see how your breasts seemed to almost pop out.
But he decides to ignore it because he remembers what you told him and gets angry again.
I can't stand listening to you anymore. I've already heard from Alfred, Jason, Tim, and even Damian looks at me ugly. I hate everyone who talks to me just to scold me. I'm not a child.
"I'm a grown man and Barbara is a grown woman too. We both said yes to that and accepted the consequences. I don't need your cheap moral lectures." My voice comes out hard and firm. "And for your information, I'm not an incredible friend, I've already proven that to you." I hope you turn around and walk away, I want to be alone.
