John could pinpoint the moment when he started to really notice what was going on with Sherlock; when he started to notice the silence as Sherlock's absence instead of silent thinking; when he started to realise that the experiments were being left out longer than they usually were and when He started to notice that most nights Sherlock didn't even come to bed until early in the morning.
He knew what these signs could all very well be pointing to. He had seen enough TV and been on enough cases to notice the signs.
And like the people in TV and in Sherlock's cases, John didn't want to believe it. He didn't want to think that a man that he had sworn to love for the rest of his life could betray him like those people had done.
Then other thoughts would come; they had married young, he had been away a long time, if he had just waited those few extra seconds than maybe the snapper wouldn't had lined him up and he wouldn't have been sent home.
Too many what ifs danced through his mind and each one seemed to twist the knife deeper into his heart, and it didn't matter what he did to try and still the traitorous thoughts John still thought that he was going barmy.
