Kurt felt so overwhelmed with a guilt he barely knew he had. He couldn't even raise his gaze up from where it was locked on his hands. "We lost Carole. It was just me and my dad." he knew these stories so well. He knew this loss. He didn't know that Blaine couldn't read the understanding on his face though... he shouldn't have even expected him to be able to. There were so many negative emotions flowing through him that he almost didn't feel grateful enough to have Blaine standing here in front of him.
Honestly Kurt never imagined that they were anything but completely in love and together until Blaine actually showed up and threw a wrench named 'Devon' in his fairytale plans. Last night he had sat on the roof with Krissy and Lydia and the few tears that made it past his defenses froze to his face as he told them that he didn't even know who he was talking to. He was afraid. The girls had flocked to him the moment they saw how south the reunion was going. They knew him well and they cheered him up decently well. Yet here the boy stood, dropping something so important like it was an after thought.
He lifted his eyes and took a long look at Blaine, staring down at his shoes. He had done a very good job of not crying up until this point but that was only because he had been beginning to manage the numb feeling of dealing with losing his love. Now that the warmth of true hope was kindling back up in his heart he didn't know if he wanted to cry or laugh and he settled on a weird mix of both.
His laugh was short and nearly sobbed out. At least he wasn't crying a lot, it was mostly just sniffling at the prick of future tears burning at his eyes, he still rose a hand to wipe away any that might try and escape. It took him far too long to compose himself and say with a shaking voice
"No..." he shook his head and dragged the back of his hand against his eyes once more in a quick swoop "no we didn't. And I didn't want to leave you. Not ever." That was his answer.
