What should I do??? please help?

ok so i have been dating this guy for a little over a year now and we moved fast in our relationship and moved in together after being together for 4 months (we both were in a situation where it was convenient for us). I was working in inventory for a store were the hours got cut back to almost nothing as the company was slowly going under. my boyfriend took that and tried to get me to leave as he didnt like me working there cause the friends i made there and a guy having a thing for me ( nothing happen between him and i, as i had no feelings wat so ever for him and dont believe in cheating). so he was on my *** to leave and finally when the b.s. got really bad and stressful and when i only got two 4 hr shifts if i was lucky a week so i left since my bf was being ssupportive for me to leave. i was looking for any type of work and a few days before an interveiw for landscaping our cars fuel pump went and i missed the interveiw after the car got fixed i was back to looking for work and where i live in the country without a car is bad enough for doing laundry, grocery shopping, etc. and when i got another interveiw that day the transmission went ( yeah i know **** box of a car, Dont get a caddy. my bfs car) anyway and since then with money being tight as my bfs pay goes to food , rent, his dui fine and his child support payments we havent gotten it fixed and its been 2 months and being out in the country there isnt anything even bike distance. with the stress of money now we arent doing so well, well its been 4 months we have ben fighting (even before i left my job) cause he has past trust issue and jealousy issues cause of past relationships and when we fight its because communication isnt there anymore and the flame has gone out is wat i try telling him and things change for abit but goes back to the same old and he fights over the fact i have no job and he calls me lazy, and useless and with his jealousy issues any guy that messages me he calls me a slut and a tramp cause they are only talking to me for one thing he says and he has made me delete friends and not talk to them cause he doesnt like them for one reason and one reason only and its cause they are guys. even my two best friends say hes unfar as when i go for a girls night or day with them he flips out everytime trying to make me cancel with them and they tell me its unfar they cant even see them cause they know i dont want to deal wit the b.s. and just not make plans with them and i have done that for him with some friends but he can talk to girls and he would never cheat on me he says. but right before we moved in together i found he was talking to his ex as he asked me to answer his phone and his ex texted saying "i miss u TOO and ur always in my heart TOO". after all that he has hacked on my facebook many of times to try to find stuff on me but doesnt and in one fight i made him sign in his to see how many girls he was talking to, to prove him wrong and a few messages he was taking **** about me to them. and he flipped out cause its been over a month that we had and i dont feel like it as the flame has gone out and with the lack of communication he's like a stranger and i dont feel right. so he thinks that since he isnt getting any , i must be putting out somewhere else. with our fights lately it has been real bad i try to go for a walk to calm things down but that doesnt work cause when i come back hes flipping out more or even fallows me down the road yelling and a window has been smashed cause he took a pic i was holding and had chucked it behinde him and it smashed the window. hes also been pissed lately with me cause i have 3 months left and i want to visit my family and friends before i go to basic training and he doesnt like that cause he wont have time with me even though we live together and have every night together but instead he hangs out across the road. the issue is that the flame wont come back and i know it since i have been trying the past 4 months for this to work. the only issue is breaking it off wit him as he makes me feel bad as he cries everytime i say something about breaking it off and i want a firendship but cant do anything if its not there but its just telling him im having trouble wit cause i still love the guy im just not in love. also he tries to say he wont be able to make it without me even though he has been without my help since i havent been able to work. plus my parents are really helping me out as they said if i move back with them then i can get my job back in construction for my last 3 months which makes me want to move more as its a job and a good paying job for that. how should i break it off with him what should i say to him that he might not flip out and fight with me
