Dick's love language was most definitely words of affirmation,he loved to tell you when he thought you looked your best,even if you didn't feel like it. He'd tell you about things he'd seen in his day or on patrol that reminded him of you,But his favorite thing to do was when he climbed back through the window and he saw you had been waiting up for him that he'd tell you how much he loved you,and he'd give you a million reasons why until you had finally fallen asleep. He loved to tell you how much he cared about you,and he loved the fact he could come home to talk to you about nothing and everything.
So when he was injured during a fight with blockbuster and loopy on pain medication he spent the entire time saying how much he loved you,telling you how nice you looked,how nice you smelled,how nice your hair felt,your skin. But one day when you were giving him his pain medication he sat up and stared at you for a long while before speaking"I wanna marry you one day"
