<human>: We've been together for about 3 years. when we met I was battling with depression and he helped me immensely to overcome it. he made me feel happy and I became confident. shortly after I recovered, we went through some life-changing events. some of it was out of our control, some was his doing. since then he entered a phase of depression and guilt and is only recently recovering. i became stronger and i supported us. he treated me badly but i stuck through it because i knew he didnt mean it. he was just pushing me away because he was hurting. Lately he's recovering and keeps saying that we will be better.
which brings me to this day. we had our first big fight and he screamed at me to leave him. it started with me ranting at him for his shortcomings.. he doesnt have a job, we don't have sex and i'm starting to feel insecure. i feel that ive been waiting for him for so long that i can't get any satisfaction anymore. im losing patience. 
am i being selfish? what should i do?

Can you give me a shortened version of the text?
<bot>: SO been treating me badly because he is depressed. he says he'll change but im not sure its worth fighting for. we just had an argument and i dont know what to do.
