AN: Inspired by lyrics from "Trainwreck" by New Found Glory and the end coffee shop scene in "Silly Love Songs". The dialogue in this is not mine only Blaine's thoughts.
Blaine felt totally and utterly humiliated. He had never felt so foolish and he found himself expressing those feelings to Kurt as they stood in line at the Lima Bean. The fact that Kurt had been a witness to that humiliation didn't embarrass him though - it was after all Kurt. Things couldn't get any worse.
"Okay, can I ask you something? Because we've always been completely honest with each other. You and I, we hangout. We sing flirty duets together. You know my coffee order. Was I supposed to think that that was nothing?"
"What do you mean?"
"I thought the guy that you wanted to ask out on Valentine's Day, was me."*
Things had just gotten worse. The humiliation he had felt before was nothing compared to the wall that Blaine had felt he had hit. If life was a train, everyone moving along to their destination, then Blaine's train had just derailed. It wasn't that he didn't care about Kurt, he did, but what they had worked. Kurt was the most important person in his life. Blaine hadn't even consider that Kurt would have those kind of feelings for him. Blaine needed Kurt in his life and he didn't want to mess that up and given the fiasco at the Gap, changing their relationship was a recipe for disaster.
How had he missed that? How did he salvage the situation now. The answer came almost immediately - honesty. As Kurt had said, they had always been completely honest with one another. Kurt had trusted him with his feelings and if there was anyway to walk away from this train wreck, then he was going to have to trust Kurt with his.
