boyfriend isnt telling me things...

so me and my boyfriend have been trying to save up for an apartment because we still live at our parents house... Well today he barely told me he joined a gym with his "friend" coworker dude.. I got mad because he didnt tell me or mention it.. And then other times hes lied to me and said he was at work when he was at home and then he doesnt tell me he takes his sister in law and her new baby shoppping for to the doctors for check ups.... he also said he never been to a strip club when i see his facebook posts from back then and hes checked in.... Idk i feel like our relationship is SHIT and its so disrespectful to me and hurts that he doesnt tell me everything he does.... When i tell him everything i do ...😡should i leave him
