How do I make my boyfriend stop his deception?

My boyfriend from California moved across country (I'm in NY) and moved in with me and my two sons. He was out of work out there and still out of work here.. I just got him a few hours a week at the office I work at. He never talks about his family I ask about them and he just says I dont know. I have never met anyone in his family, I have never spoke to anyone in his family. I used to buy him pizza and such every Friday when he was in California. Bought him a computer and a laptop for his birthday, he is loving and says ll the right things, but whenever I asked him what did you do today he would always say look for a job or spent day with Mom, or just nothing. He left his cell phone in my car I looked up a picture of my son to email it to myself and he had pictures of all these people on there. His Mom his sister.. who he says he doesnt talk to. He had all these calls from them he told me he doesnt talk to them. He has been telling his mom he came out here for a job and she doesnt know about him even having a girlfriend. She asked him told him how much she missed him, wanted to make sure he was ok he just said he was busy working and no girlfriend. I shouldnt have read the texts but all the secrecy just overwhelmed me. I have him living with me and my children. I was curious about him. I also found out he set up a emeting with his ex a few days before the big move out here.. This is the woman who broke his heart yada yada. I KNOW READING HIS MESSAGES WAS WRONG.. But isnt it wrong to tell your family a bunch of lies and lie to me about everything for over a year? Do I tell him I know everything and tell him he has to be honest and give him a chance or just make him move back to California. I feel like he is a shamed of me and just using me for money. =( I wish I hadnt ever been curious about his life and relationship with his family. I jsut wanted to be a part of his life. Now I feel like Im some dirty secret.
