My boyfriend is depressed.

We've been together seven years, to be honest it's never really been easy. He's always been "controlling" I stupidly moved in with him after 2 months and it more or less started straight away. Not letting me go out on my 21st birthday because my friends are "slags" anyways... He has his good points of course and I do love him always have. These past 2 years he confided on me that he was depressed. I took him to doctors ect nothings ever got any better. He doesn't take any medication now he's just plodding on. Doesn't even leave the house. Doesn't work to be honest he's never liked any job and the longest one he had was because he had to cos if he quit he wouldn't get JSA. I'm currently working 60hours a week to pay the rent and feed us. But cos I'm always tired after my 12 hour shifts I'm miserable? Tonight's an example. Sat watching emmerdale and he starts throwing cigeratte ends at me (not lit) one by one, told him to stop numerous times so I throw them back which he didn't like and kicked off. That's what he does you see. He'll call me names like crank, skank, freak, weirdo, dog but if I dare to insult him back he won't speak to me for a week. Iv no patience anymore. I want to leave but if I left what would he do? He wouldn't be able to stay in the house were in cos it's in my name and I know he won't keep up with rent. Iv got to the point where I can not be bothered any more. I've told him so many times I don't like the name calling and him playfully "poking" me. I'm embarrassed around our neighbours. I can't even be bothered with myself!! Help
