Jason knew it was for the better. He had to break up with you. You weren’t safe with him. Not only because he was a vigilante, but because of the things he had done. The people he had killed. He didn’t even know why you put up with all of his shit for so long.
He was broken. The Joker managed to break him, to make him doubt himself. The Joker was mentally unstable, and being with him for over a year, being tortured, and the fact that the Joker sometimes acted like a paternal figure completely messed up his mind.
He wasn’t good for you. He was closed off, he argued with you about his insecurities, and more than once he questioned the relationship but was too selfish to break up with you. But now he had to do it.
“I just think we’re not compatible,” he says, sitting in front of you on the couch as if he had already tried to put distance between the two of you. He fidgets with his hands and looks away from you avoiding your gaze. He couldn’t bear to see your face while he broke your heart. “I think you would be better off with someone else,” he murmurs.
