Dont know what to doo..?

i have been moved in with my boyfriend,, 4 months. I am home sick I moved across the state to be with him. We love eachother. Atleast i think i do.. we did want kids together. But ever sence last friday he over dosed on xanax and bud light. he would of died if i wasnt there to save his life. Sence then I am totally turned off by him and I want to go home. I have never delt with a man being like this. Or depressed I knew he was cause he told me but i didnt think it was that bad. Now he is blaming me that i helped him be like that cause i ignored him one night cause i was having a problem and its not all about him sometimes and he should ask me whats wrong insted of consuming a bunch of drinks.. Hes depressd cause he has some problems.. Not cause of me. he and i havent been together that long to have him be depressed about me..? so I am all the way over here i do have someone back home i can stay with my best friend. Should i just keep it quiet and save up and then let him know??? ahhh i want to go home now. just wish it was that easy.. any ideas??? NO RUDE COMMENTS PLEASE.. Thank you ...
