He doesn't tell her he's sorry anymore; it only seems to upset her, to distress her, and he won't hurt her any more than she already is. Draco waits until she has slipped into the unconsciousness that isn't really sleep, and then he whispers it in her ear over and over like a penance, listening to her heart beat and her breath whistle and rasp. Tells her that he loves her and he's sorry for it. That he's sorry that he failed her. That he's sorry for everything, and that he wishes that Voldemort had killed him, instead of taking his hand. That he wishes they had left him to bleed out on the Manor floor instead of staunching the blood pumping from his wrist. Because then she might not be here – she might be safe. Everything might have gone so differently, and he is so, so fucking sorry.
