Should I leave my boyfriend?

We have been together for 5 years and 3 months, when I graduated from high school 3 years ago I moved into his moms house where we still live, (right down the street from my grandmothers house) since I was having a hard time with my stepdad and family issues at my mothers house I thought I would have been better off living with him... So now our relationship has gone through it all and I mean all, except cheating well on my part I know for a fac that I would never cheat on him and never had as for him he says that he has never cheated or anything of that nature, but latley our relationship has been so bad that I don't even know whats up from down. I have been the only one working for almost 3 and a half years now and it is so stressful and I support us in every possible way although he says that I don't provide or do anything that he can do it on his own. We argue almost everyday and its all because of him he criticizes me on how I look what I wear, talk, I mean EVERYTHING... And to me thats super hard since he is the only person I feel should never tell me things like that. When ever I ask him to let me see his phone or anything that has to do with "his" things he gets a little defensive and over protective, but when it comes down to my things he expects for me to give him everything. Another thing I pay for our cellphones and my rule is if I call him or text him I expect for him to reply back to me not in a second, but I expect for him to reply sooner than 30 min or so and he still can't understand that only rule. He is also a liar I will tell him everything and nothing but the truth, but to him he lies about everything and he has also pawned a couple of his sister jewelry that she had lent his mother, A LOT of lies and broken promise. I feel he cut my love for him in half, but I still feel that I love him. He says he's going to change but I never see anything change. I know I have a major part in the fight, but it is super stressful when only one person works and does mostly everything and the person gets to have fun and do other things... I also tell him to spend more time with me and that his friend can wait since I don't really (never) got out with my friends he get mad and says its not a big deal, (all of his friends he grow up with pretty much and they all live around or ares, street) he is always outside drinking,smoking or just hanging out and that bothers me... I don't know what to do any advise...??? I think he will change, but I;m not sure if he will... UGH...
