Alcoholic Boyfriend!!

Hi I am 19 years old and have been with my 25 year old boyfriend for over 4 year, he started drinking cider when he was 15 and has drank cider everyday since then which is 10 years he has drank non stop for now! Everytime i ask if he will get help to stop drinking he just starts an argument and says I am trying to rule his life and that he only drinks because of “stress" and because he's had a “hard life" he also says he isn't an alcoholic he's just a binge drinker, I am getting really fed up and he says he wants to work but hasn't even looked for a job, he doesn't let me go out the last time I went out with friends I was 15, he is very controlling and tells me he will do something silly to himself if I leave him, I don't want us to break up but I can't sit and watch him drink his life away, he always pours a cup of cider as soon as he wakes up, I am really stuck and asking if someone could give me advice please?
