Is it me or do we need to break it off (long but please read)?

I have been dating this guy for just about five mths be five mths the 27th of this mth the first mth was great he was one of the best guys anyone could for and I know a lot of people say that but with me its the truth. We lived three hrs from one a other up until last mth when my real dad beat the crap out of him for no reason and my family tried to keep us apart so I move to south carolina with him we live with his friend and me and his friend are friends and he acts so insecure about it like his friend called my phone one day and my boyfriend got all mad when our friend called his phone but he was sleepin and didn't answer so he called my and my boyfriend actted like it was a crime. The other problem is his ex this girl has started so much crap that it has just about caused us to break up he still talks to her but yet if I talk to a guy friend he gets all mad and tells me I shouldn't do that but look what he does he talks to his ex that supposely treated him like crap and was abusive. He constantly yells at me for sleeping I get up at like 5am fix him lunch for work and go back to sleep til nine or ten and he gets soo mad at me for it he goes on and on about how I sleep to much and I don't care nothing about him.all we do is argue cause he is always on my case no matter what it is he constantly puts me down and I tell him if u don't like the way I do it then do it urself. To me he is very demanding if my phone rings he runs to it but I do it to him he gets mad if anyone shouldn't trust someone in our relationship its me not trust him he has lied to me so many times its not funny a other thing is there's a change I could be pregnant and he demands me to get an abortion I don't belive in that and his excuse is oh well we don't have a big enough car for a baby and am not giving up my truck for no baby he is 23 years old I thought u were grew up at that age am 19 and know if am able to spread my legs I better be able to deal with the responbitles that come with having I just don't know what to do anymore even his friend saids he's demand and insecue and damn I see it now I love him and want to be with him but talking doesn't work I have threated to leave him once and he begged me to stay and told me he would change but that's been a mth ago please give me some advice I dontknow what to do anymore
