Trust. It was a funny thing. He considered himself extremely trust worthy and yet found it very hard to trust others. Or maybe he did not always find it hard. Maybe it was when his mother passed away after promising his eight year old mind that she would always be there for him that he really started to close himself off from others and took their every word with a grain of salt.
He changed everything, the dapper boy in the blazer and tie who for some reason trusted him even though he was clearly a spy and not a new student. For some reason the bright hazel eyes and warm smile drew him in and earned his fleeting trust in a matter of minutes when others had been trying without success for years. He told him everything from the mundane details of his day to the darkest secrets buried within his heavy soul. The only thing that Kurt had ever kept to himself was his sheer love for Blaine but even that could have been kept closer if he had really wanted it to. Even with the potential embarrassment of rejection, he still trusted the Warbler enough with his feelings to know that all would work out fine in the end.
The end. That's another funny thing. The way it can drag on and on so its arrival is a relief or it can be sudden, unexpected and feel like the story had been severed agonizingly prematurely with a knife. When the foundation of a relationship is trust though and that rust is broken, sometimes there is just no other way then to wield the handle yourself.
Blaine was just like everybody else now. There was nothing special about him. He was just one more person added to the sea of those who had betrayed him. The wound would be slower to heal this time though. Every time he thought about the boy, all of the happy memories came first and he would fall in love with him all over. It would be then, once he finally felt like maybe he had been the one who made a mistake, that reality would sink in again, the knife would carve again, and the realization that none of those happy times mattered any more would hit him. They did not matter because they would not have happened if he had not been able to lay his trust in Blaine and now the boy knew too many of his daemons for Kurt to ever be comfortable creating new light and laughter.
