Author's Note: This will most likely be a threeshot. Set after the war, with Voldie long dead and gone. :)

Shock. That was the only thing that registered in his mind. Absolute shock. From his hiding point across the street, Draco saw Harry, cleverly glamoured as dirty-blond, smiling sweetly at another man, who had his arms draped around his lover's waist and his head buried deeply in Harry's neck. Draco watched as the two kissed with a passion, watched as Harry's fingers hooked themselves in the back pockets of the man's trousers in a way that Draco himself had become so accustomed to feeling. He watched as Harry nibbled delicately on the man's neck, which had arched back in pleasure. There was no doubt that this was not just a random occurrence. No, these two had an air of practice about them, an ease which left Draco with no qualms that this was not the first time Harry had met with the man. A hard lump formed in his throat and he found himself blinking back stinging tears. He watched as Harry intertwined his fingers with the other man's and pulled him into the waiting flat. Draco sat in his secluded corner for more than an hour, his frame shaking with despair. He should have known. He should have known. The words repeated themselves over and over in his mind... Harry working overtime...Harry grabbing a few pints with his fellow Aurors ... Harry coming home, smelling like sex, like someone else's sex, when he was sure the last time they had made love was more than a few hours ago. Draco wanted to slap himself. The clues were all obviously there. He'd just been too blind to see them. He sneered at himself. He was pathetic.

Draco wandered idly around the flat that he and Harry had shared for the last five years, vaguely noticing that this would be the last time he'd ever spend time in the place. He rubbed his fingers along the counter of the kitchen, remembering bitterly all the times he'd cooked for Harry and ended up eating alone, waiting for the coming excuse of, "Sorry, love, worked late tonight."

"Late, my arse." Draco murmured, ignoring his suddenly watery eyes. His whole life had revolved around the other man. He had worked so hard just to please Harry, he'd made friends with all the Gryffindors, he'd publicly renounced his father for the love of the other man... all to be wasted. But he was done now. As soon as he had gathered himself back under control, Draco had immediately Apparated to their flat and emptied out his closet and all his drawers, shrinking his belongings to fit in the tiny suitcase he had brought when he had moved in. Draco had Floo'ed Blaise directly after he was done, only partially explaining what had happened. Blaise, being the perceptive friend that he was, knew that Draco was upset and wisely asked no questions, simply asking when the other man would arrive. His only response was, "Soon."

Now Draco was only waiting for Harry to arrive. He wanted to see the unfaithful, lying prat's face as Draco told him he was the one leaving Harry. Almost as soon as Draco had thought the words, the front door opened and he grimaced, his stomach clenching with nerves.

"Draco?" Harry called out and he heard the clink of keys as Harry set them down on the coffee table. He flinched. He knew Harry's habits by heart. "Love, I'm home!" The endearment, which had not so long ago made him swell with happiness, now made him recoil. Draco waited for Harry to approach their bedroom and tried not to let his emotions flit across his face as the other man strode into the bedroom, grinning widely. The grin slid off his face quickly however, as he took in Draco, who was not wearing his usual silk pajamas but instead a black traveling coat and sturdy denims, seated primly at the edge of their bed, a suitcase packed tightly at his feet.

"What's going on?" Harry asked, puzzled. He motioned to the suitcase. "Are we going somewhere?"

"I am." Draco answered calmly, picking invisible lint off his coat. "I'm leaving you, Potter." He saw Harry's face stricken with disbelief.

"Excuse me?"

"I'm leaving you." He repeated evenly.

"This isn't funny, Draco, stop it." Harry said tersely.

"I don't see anything particularly funny in the matter either, Potter." Draco shot back. "I've packed my things and I've got somewhere to stay. I just stayed to leave you those." He jerked his towards the silver keys that lay in the center of the king-sized bed. Harry's eyes widened with shock as he realized how utterly serious Draco was.

"What did I do?!" Harry cried desperately, pain lacing his voice, as he stalked forward and dropped to his knees in front of the other man. "Draco, tell me what I did, I promise you I can fix it!"

"I saw you." Draco whispered and Harry leaned back on his knees, his face paling considerably. "Do you hear me, Potter? I. Saw. You."

"No... I don't... no..."

"Surprised, are you?" Draco laughed brutally. The sound was foreign in his ears.

"Draco... I can explain."

"The hell you can." Draco said viciously, shoving Harry as far away from him as possible. "Don't you understand, Potter? I saw you shove your tongue down his throat! I saw you suck his neck like it was a lolly! Don't you get it?! I saw you! And now..." He let a sneer take over his features. "I don't want anything... anything to do with you."

"No!" Harry cried hysterically, tears rolling in rivulets down his cheeks. His whole body shook as he scurried forward on his knees, grasping on to the hem of Draco's robes. "Please, Draco, it didn't mean a thing, I swear it!"

He laughed that hard, brutal laugh again and stood up. His own eyes were blinking back a fresh wave of tears as he didn't look at Harry's broken face. "Was I not good enough for you, Harry? Didn't I try to redeem myself for you, just so we could be together?"

Harry flung himself away from Draco and lay in a crumpled heap on the floor, sobbing. "I love you, baby, I love you!"

"Don't you ever say that to me again." Draco said fiercely, the knot in his throat growing steadily. "Do you hear me? Never. You don't love me, Potter. If you had loved me..." His voice cracked and he trembled. "If you had loved me... you wouldn't have cheated."

"Don't leave me." Harry pleaded frantically, his glasses askew and his mouth quivering. "I'm nothing without you, Draco, nothing!"

Draco ignored him and picked up his suitcase, walking to the door. He was followed by a desperate Harry, who continued to cry in desperation.

"Don't try and look for me." Draco warned him. "This is the last time you'll ever see me. I don't want anything to do with you, Potter, not any longer. As soon as I can get over this..." He swallowed. "I'll move on. With a person who can appreciate me."

And he walked out of the flat, leaving a broken and sobbing Harry Potter in his wake.

A/N2: So? What do you think? I'm pretty anti-love at the moment, so this little plot bunny seemed fitting, considering my mood. I'll post next chapter soon, I promise. The most you can expect is around a total of 3-4 chapters, I'm thinking. But no worries! Happy ending is ensured... maybe. ;)

I'd love to know what you thought, so please, leave a review!
