The house in the middle of suburbia with the white picket fence, the luscious green lawn and barbecues was quiet. Not the everyone-was-asleep quiet but the devoid-of-life quiet. There was no water running for a shower, no classic rock belting out from any of the other rooms, no sounds of laughter, not anymore. If you listened carefully, you may have been able to hear the sounds of quiet sobs as a broken hearted lover cried over his lost love. He would often hear and feel the echoes of the man he loved when he closed his eye and he'd feel as if his celestial heart had been ripped out. He closed his eyes as he curled on their bed after being hit by the usual echo of Dean Winchester's laughter. As he laid there totally unmoving Castiel started to sob as a memory attacked his conscious mind. A memory of what had caused the happy ending to turn sour.
-Flashback-
Dean and his holy tax accountant boyfriend were stood in their bedroom after visiting Lisa Braeden, a friend of Dean's. Castiel was pacing and Dean knew from experience that it meant that Cas was thinking something over far too much.
"Cas what's going on?" Dean asked confused as he approached the agitated angel.
"You are cheating Dean." Cas accused, not being bothered to keep the anger out of his voice. Finding the accusation completely insane, ever since he'd fallen for the angel he hadn't found anyone sexually attractive other than Cas, Dean snorted his laughter. He wasn't interested in anyone else, he just couldn't, and not even when he saw Lisa did he once think about cheating and Lisa was beautiful, even his gay brother could appreciate that.
"I'm not Cas. I couldn't even if I wanted to." Dean protested truthfully. Little did he know that their bond was forming and Cas was feeling possessive over his boyfriend which caused the jealousy over a platonic friendship with Lisa Braeden. He could see that his angelic lover didn't believe him and the truth was that it hurt Dean knowing that because he'd lied to Cas before, he wouldn't be believed again.
"You're spending a lot of time with that Braeden woman. What am I supposed to think Dean?" Cas asked obviously worried that Dean was lying, but this just hurt the hunter more.
"Yeah I am, because I feel responsible for the kid. When I met up with Lisa again and I saw Ben, I thought he was my kid at first, he's not, but ever since I saved him from the changelings I've felt like I should be there for him, to be that father figure I never had. Dad was too busy hunting to be there for me and Sam when we needed him. I screwed up with Sam and it almost cost him his life, I can't let that happen to Ben, Cas. I'm a father without a child, can't you just please let me have this chance? Lisa is grateful that I help out with Ben, but there is nothing going on between me and her." Dean told Cas, he was laying all his cards out onto the table in one of the rare moments he decided to let people into his heart and see what he saw. He only trusted Sam and Cas to truly let into his heart, of course he would be totally honest with his kid brother who throughout the years had always made Dean remain human and keep him grounded when he needed it, but the real surprise had been Cas, who to Dean had only been the holy tax accountant pain in the ass, but over the years since coming back up from the pit he began to trust the angel and after he started to trust him, he started to fall in love with the angel.
"Cas I love you, but I…I can't do this every time you feel jealous." Dean cried finally breaking down with the hurt he felt at what Cas was accusing him of. He picked up the duffel bag he'd let gather dust in the bottom of the closet and without looking at what he was taking he began to thrust clothes into the bag staining the material of the bag with his tears.
"I…I have to…leave." He cried walking away and to the surprise of both hunter and angel, Cas didn't try to stop him. The sound of the front door slamming shut and the Impala rattling away struck Cas like a knife and caused him to crumple and start to sob as he realized for the perhaps the first time since the arguments had started that he was making a mistake. He felt like he was in agonizing pain as he cried for hours missing the hunter he loved.
