I just read the arch with Kory's wedding, and I feel terrible, so I want to write my angst dickkory headcanons.
for a very long time, Kory blamed herself for allowing this wedding to happen. and even after the return of her relationship with Dick, she could consider that she did not deserve his love. sometimes she was distant. in the first months, when they slept together again, there could be such a scene:
Dick was falling asleep, but Kory was still awake. Dick is lying with his back to Kory, and she's sitting next to him with her legs tucked up, just watching. she really wants to hug him tightly by the shoulders like before. she reaches out her hand, wanting to touch him, but stops herself. Instead, she hugs her knees, buries her face in them, and begins to sob softly. shortly after that, Dick wakes up. the first time he heard Kory's sobs in his sleep, he started asking her what had happened. Kory just sobbed and said something unintelligible about how she didn't deserve to be with him, that she was to blame for him, and Dick should hate her. after a while, Dick stopped asking. he just sits down next to her and hugs her tightly without saying a word. when Kory calms down a little, he lies down and puts her next to him, still holding her tightly to his chest. he doesn't fall asleep until he is sure that Kory has fallen asleep and that he has wiped all the tears from her cheeks. Dick won't admit it, but at these moments he's also crying softly into her hair. he couldn't fall asleep before Kory for a long time because he was afraid that she would feel bad again. and he no longer slept with his back to her.
