so Sherlock had history of doing this..dating people to solve a case and get close to the actual person who committed the crime..you knew of this but you thought you were different you both worked good on cases together before you started dating, you worked well with each other and you were both on sync which was even surprising for John. unfortunately you were just another tool..right now as you stood before him trying to wager wether if you were more mad than heart broken as he sat before your telling you how he basically just used you to get close to your brother who had also unfortunately killed some man with little ways of access to getting to him..you were just another key

Sherlock,”I do hope you understand that i needed to do this.”he said looking at you like if none of it even mattered to him.
