Hey everyone. This is just a little fic I was thinking about and thought I would write. See notes at end for more info.

Anyway, hope you enjoy.

WARNINGS for infidelity.

I do not own Harry Potter.

Chapter 1

Harry made his way into the apartment that he and Draco shared. He had had a busy morning at work but had managed to get away a little earlier and was planning on cooking Draco something amazing for dinner.

He walked into the kitchen and placed down his shopping bags when he first heard the noise, a loud moan coming from their bedroom.

That's strange he thought, Draco said he would be working late today, hence the reason Harry decided to come home early and surprise him with a special dinner.

Harry made his way silently down the hall to their bedroom. He was quiet as only someone who had spent most of his formative years running and hiding can be. He heard it again, another loud moan and the sound of material rustling.

Harry felt his heart start to thump in his chest, his palms growing sweaty, what was going on here?

He opened the door to his and Draco's bedroom and froze at the sight that greeted him.

Draco naked on the bed, slowly fucking in and out of Theodore Nott. Theodore was writhing below Draco, gasping for breath and moaning so loudly Harry knew Draco must be hitting his prostate dead on.

Theodore fucking Nott, his brain processed. Theo had come to them only yesterday seeing if they would be interested in forming a triad relationship.

Draco and he hadn't even had the chance to discuss the possibility, to go over the pro's and con's of such a decision. Well, it looked like Draco had made up his mind already.

He felt strangely detached as he watched his boyfriend of two years fuck another man, some part of his mind knew that he must be suffering from shock, his mind trying to shield itself from the incoming pain.

He cleared his throat loudly, "just what the fuck is going on here?" Harry asked, his voice eerily calm.

Draco screamed and threw himself off the bed and off Theo so hard some part of Harry registered that it must've hurt, while Theo quickly grabbed a blanket and pulled it up over his naked body. Harry's favourite blanket he noted, the one Mrs Weasley had knitted for him when he had first moved into his own place. Draco quickly grabbed a pair of pants and pulled them on.

"Harry" Draco said, his face ashen. "I wasn't expecting you home so early."

"Well, that much is clear. I decided to come home early and cook you something special for dinner since you said you were working back this afternoon. I can see now that that was a lie." Harry let the accusation and anger start to slip into his voice as he spoke, taking vindictive pleasure when Draco winced.

Theo spoke up now, "this is my fault Harry, I asked Draco to meet me. I just wanted him so much, want you both so much, I convinced him this was a good idea."

Harry sent a scathing glare at Theo who flinched away from the harsh look.

"Oh, please" Harry hissed eyes narrowed in anger. "Draco is a grown man, more than capable of making his own decisions, more than capable of saying no, it just seems that he did not want to say no in this instance."

Here Harry turned furious green eyes on Draco. He was the one Harry was truly upset with, sure he was mad at Theo, but Harry wasn't in a relationship with Theo he was in a relationship with Draco and Draco had cheated on him. They had built a life together and Draco had thrown it all away, he felt like a knife was piercing his heart at the thought.

"It wasn't like that Harry" Draco pleaded. "We… we just thought with talk of us becoming a triad that it wouldn't be that big a deal."

Harry stared at Draco in complete and utter shock before the calm that he was desperately holding on to shattered and his anger overtook him like a tidal wave.

"What complete and utter fucking BULLSHIT!" Harry screamed, his body shaking with rage. "He only asked us yesterday about becoming a triad, we hadn't even discussed it yet Draco, and you claim that you thought that fucking Theo now wouldn't be a big deal!? What? That I would just be OK with you sticking your dick in someone else behind my back, someone that we are decidedly not in a relationship with, regardless of yesterday's conversation! I know you aren't that stupid Draco." Harry scoffed.

"Or was this the plan all along?" Harry said. "Have you two been wanting to be together for a while now and the suggestion of a triad was just the means to an end?"

"What? No Harry. I love you. I love you so much" Draco said desperately.

"I love you too Harry" Theo said, and Harry could see that he was only just now registering how serious the situation was. "I want to be with both of you."

"Huh, that's funny" Harry said with a sneer that would've rivalled Draco in his Hogwarts days. "Where did I factor into this then?" Harry said waving his hand around the room at the discarded clothes and dishevelled bed.

Draco and Theo shared a look, both unsure what to say, but this only served to make Harry angrier.

"That's right I DIDN'T!" Harry roared.

Harry took a deep breath; he felt his eyes start to prick with tears. "I can't believe you would betray me like this Draco." This time Harry's voice came out sad and small. It seemed that the quietness pained Draco even more then the yelling had.

"Harry please" Draco said urgently. "You don't want to be with Theo, then I don't want to be with him either. I couldn't care less about him; you are the one I care about. We can get through this baby" Draco said, as he took a hesitant step toward Harry. "I will never see or speak to Theo again if that's what you want."

Harry looked up at Draco with sad green eyes, he glanced at Theo, noticing the pained expression on the others face at Draco's words.

Harry just shook his head, his heart breaking.

"It…it's to late Draco" Harry said with a sob. "How can I ever trust you again?"

Draco ran forward grabbing Harry by the arms and shaking him slightly.

"No Harry, you can trust me. Please, don't do this."

Harry pushed Draco away ignoring the devastated expression on the others face, the anger had faded and now all he was left with was bitter sadness.

A part of him just wanted to forgive and forget, but he knew himself. He had been lied to, had things kept from him to many times to just forget and move past this.

Harry waved his wand and his things from all around the apartment started flying into his suitcase. Clothes, books, photographs, everything landed in his magically expanded suitcase and the lid fell closed with a soft click. Draco stood nearby and watched, sweat still dripping down his body from his earlier activities, his eyes desperately sad. The sight making Harry feel both mad and sad.

Harry cast a feather light charm on his suitcase and picked it up.

"Goodbye Draco… I hope it was worth it."

Without another word Harry apparated away.

I read quite a lot of fanfics and I've read a few where Harry gets hurt or cheated on and he just forgives them, sometimes doesn't even get mad. Even though I like the story's I thought I would write one where he does get mad.

I will continue the story, but I haven't decided if Harry will forgive Draco and they get back together possibly with Theo or if he moves on with someone else. I'm honestly leaning towards him moving on with someone else but please let me know what you think! Would love to read people's thoughts
