Thank you, everyone, for the reviews and follows, it is greatly appreciated

As a side note, I would just like to clear something up. In no way am I writing just for the reviews, I am writing simply because I love writing, and I love Destiel. If in any way anyone was offended by me asking for another review before continuing this story, then I truly am sorry. I just wanted some tips on how the story should unfold, and how it was being received. Getting a review criticising my authors note really knocked me for a while, so I do apologise for any offense this caused anyone.

So, lets see what's in store for Dean and Castiel after the Arch-angels shocking ultimatum...

When Dean woke, he first heard the rain pattering against the windows, then he heard the smooth purr of his baby, roaring down the highway, and then he heard the sobbing of an angel.

Spinning around so fast he got whiplash, Dean was faced with a sight which broke his heart. Castiel, his Castiel, was crying, tears pooling in his blue eyes and running down his cheeks, as if escaping the prison of his irises. Dean had found himself locked up in those eyes one too many times, unable to look away or break the angels intense stare. To see them stricken and filled with tears make Deans own eyes begin to pool with salt water.

"Cas, pull over."

The car swerved and spluttered to a halt; the truck behind them honking angrily. But Dean didn't care; the only thing he cared about at this moment was Castiel.

As soon as the car stopped, Castiel was hunched over the steering wheel, shoulders shaking and loud sobs filling the car's interior. Gently pulling the angel into his arms, Dean rocked the other man, murmuring words of consolation and love in his ear. Castiel had buried his face in Dean's shirt, breathing in the scent that he would soon never smell again. Because he had made his decision. To protect Dean, he must leave him.

Once Castiels sobs had calmed down, Dean asked "Cas, baby, what's wrong? Please, tell me!"

Dean felt helpless, unable to help the man he loved, and at this moment in time, he had never felt so human.

Castiel hiccupped. "I love you", he breathed into the nape of the hunters neck.

Dean gasped. It was the first time Cas had ever said those words to him, and while he was filled with happiness, he also knew that something was very wrong, something that would rip him apart from the inside, an injury so great that it would challenge all other injuries Dean had ever sustained in his life, and emerge victorious.

"I love you too, Cas, so much. That's why you have to tell me what's wrong, its killing me." Dean whispered.

Castiel took a deep breath. He knew it would take all his strength to tell his beautiful hunter that he had to leave, that he could never return. He knew Dean would never understand, he would have no concern for his own safety, he would risk his life to stay with Castiel. He was so brave. But Castiel knew this would break him.

"Dean, I have to leave."

At first, Dean didn't comprehend. "Oh okay, you go and do your angel duties. Will I still see you tonight?"

No, thought Castiel, you will never see me again, if I allow the Arch-angels to do this to us. Was he brave enough to leave Dean? That was a question he was able to answer with ease, no, he was not. Would he leave Dean to protect him? This question was equally easy to answer, yes, without a second thought. The hunter meant the world to him, and he would always strive to protect him.

Castiel spoke. "No Dean, you will not."

Now Dean was becoming worried. "Uh...Cas? Why not?"

Castiel steeled himself to tell Dean the truth. "The Arch-angels have forbidden us to see each other. They do not like it, me fraternising with a human, they see you as unworthy of my love."

Dean laughed, harshly. "So? Fuck those sons of bitches! Who cares what they think?"

"I don't, Dean. But they have threatened to kill you if I do not leave you. I am to leave and never come back. I have to do it Dean, I have to protect you."

Dean's face changed. From anger, to understanding, to grief. "No Cas." Dean choked, "You...You have to stay with me, and we'll figure it out together, okay? Okay?"

Castiel shook his head sadly. "No Dean, I will not put you in danger. I love you too much to ever do that. This is it, Dean. This is goodbye."

Castiel could see that Dean was about to protest, and so he silenced him with his lips. The kiss was desperate, warm lips sliding over each other, tongues entwined. Both men knew that this was to be their last kiss, and so they each put their heart and soul into it, trying to tell the other man how much they loved them with a kiss alone.

When Castiel finally pulled away, he looked directly into Deans beautiful hazel eyes. "Dean, you are my only love, the only person who has ever broken through my walls and showed me that I am capable of emotion." Castiels eyes shone with tears. "I love you, Dean Winchester."

Then, with a flutter of wings, Castiel was gone. And all Dean could do was cry for his lost love, and pray that one day, he would come back to him.

Oh no! How will they cope without each other? Will they ever be together again? Keep reading to find out;)
