A/N: Here's some sweet sadness. Really short, jsyk.

Blaine sighed contentedly as he snuggled further into Kurt's side. "What would I ever do without you?"

Kurt shifted from his previous prone position so that he could sit up and freely run his fingers through Blaine's loose curls. "What do you mean?"

Blaine wiggled when Kurt's fingers pressed on the sensitive spot of his scalp that sent a wave of pleasure down his spine. "Nothing really; just that I love you and you're a huge part of my life and I'd never want to live a day without you by my side."

"We all die someday, Blaine. Some sooner than others."

Blaine involuntarily raised his eyebrows. What was Kurt going on about? "Yes," he agreed cautiously, "but what does that have to do with us?"

Kurt sighed before responding, "We're humans, Blaine. I'm simply pointing out the fact that humans die. We don't last forever; someday one of us will be gone and the other will be alone."

Blaine pulled himself and looked Kurt directly in the eye. "Why are you saying that?"

Kurt averted his gaze. He simply couldn't look into the glowing eyes of his boyfriend and say what he was thinking. Kurt was just having a moment where his negative thoughts outweighed all the positives. Even Blaine's intoxicating presence couldn't always keep those darker thoughts at bay, despite how much better he made Kurt feel.

Blaine grasped Kurt's chin and raised his head so that their gazes were connected again. "Kurt? Baby, is something wrong?"

Kurt shook his head as best he could with Blaine's grip still firm on his chin. "No, I'm fine. Everything's fine."

Kurt's voice was soft, tipping Blaine off to the fact that everything was not fine. "Kurt, you can talk to me. We tell each other anything, right?"

Kurt nodded. He thought back to when he had first met Blaine all those years ago on that staircase in Dalton. How, even though they had barely met and Kurt was spying on the Warblers, Blaine still took Kurt out for coffee and helped him with his problems. How this gorgeous man loved him, despite all the ups and downs of his past. How he had confided in Blaine with secrets that not even his father knew. In those first few months, Blaine had become Kurt's world and the attachment only grew stronger with time.

Blaine nodded encouragingly. "So, why don't you tell me what's bugging you?"

"I just…" Kurt sighed, but refused to let himself bury these gnawing thoughts away any longer. Blaine would understand; he wouldn't judge. "Today's the anniversary of my mother's death and it got me to thinking."

Blaine squeezed his boyfriend's hand in an attempt to comfort him. Talking about his mother was something that was still hard for Kurt; it probably always would be. "Thinking about?"

"What I would do if I ever lost you."

"Oh, Kurt," Blaine replied softly. "Baby, you'll never lose me."

"You can't promise me that," Kurt sniffled.

Blaine wrapped his arms around Kurt, encompassing his boyfriend in a cocoon of love and comfort. He smiled softly as Kurt snuggled further into the embrace, his head leaning down to rest on Blaine's shoulder. Blaine had known about Kurt's insecurities previous to this, but he'd never known they were so poignant, so at the surface of Kurt's thoughts.

"Kurt," Blaine made sure to have Kurt's full attention before he continued. "I know I can't promise you that I won't ever die or get injured in some way because that's unrealistic and I won't put you through that. But, I will promise that I will love you for as long as you'll have me. I can promise that I will stand by you through the highs and the lows. I can promise that no matter how tough life gets for us in the future, you will always have my heart."

Kurt wiped his eyes. The words that Blaine had just spoken were somehow exactly what Kurt needed to hear in that moment. To be honest, Kurt wasn't exactly sure where this sudden sadness was coming from, but he knew that his boyfriend was being completely sincere. Blaine would never leave him intentionally; Blaine would never stop loving him either. To hear those words come from the love of his life validated something for Kurt that until then he didn't know he'd been feeling insecure about.

Kurt nuzzled into Blaine's neck, kissing the skin there and whispering in a soft voice, "Thank you."

It had been just barely audible, but Blaine had heard it. He smiled and pulled Kurt closer. If there was one thing that Blaine Anderson was more than happy to do, it was to hold Kurt Hummel in his arms.

"And Kurt?"

"Yeah?"

"I'm not going anywhere."

"I know."

"I love you, Kurt."

"I love you too, Blaine."

A/N: Wow, no idea where that came from. Well, I kind of have an idea where it came from, but that's not the point.
