He left me...

My boyfriend of almost a year just left me. Everything was great in the beginning and he moved in fairly quickly. Then it started with him lying... doing things behind my back and this has carried on for months. Everytime i tried to speak to him and the what he is doing that hurt me , he would apologize.. and then it got to a point where he stopped apologizing for what he did and started getting angry with me everytime i had a problem with him lying or hiding things from me. He told me im just trying to control him and it feels like he must stop doing everything for me. Which was far from true. He made it out like i am wrong and left me cause we fight too much. I am broken. He hurt me the whole relationahip, he then left me and is completely fine and here i am crying 24/7. How is that even fair ???? I start work again tomorrrow and guess what. I work with his sister. I dont know what to do... i am broken.
