Am I bad gf and person please help please answer?

So I've been with him for four years. I'm not perfect but I try my best to make him happy I go out of my way never miss one call even if i was fast asleep, learned to cook for him, always pleased him. I remember everything he liked and did by best to always make him happy. His been stressed out lately and so have I. And we do tend to argue when were stressed only this time it was really different. He called me in the morning telling me to get up. He told me to check my account he wanted to know how much money I have. (He got into an accident earlier, he moved a friends car brakes fail and crashed into two cars he was to pay for the damages. Were both poor, live in the barrio) So he told me If i can pay our cell phone bill I said id check when I get up. He got mad and told me to check now. So i said okay ill use my phone ill call you right back. He got mad and eventually agreed. So i checked, called him, I told him I had just enough to pay my bills. He got mad and said that he thought I would be there for him and I turned my back on him. I felt so awful I asked my mom to led me 40 so that I'd have enough. I paid, and called him. Told him not to worry, I thought we were good. But latter on he ignored my calls. He latter text me. Telling that I hurt him that I basically betrayed him. He said that I'm awful and that my love didn't matter because I couldn't be there for him. I told him I loved him and that I always try for him, but he denied it all, telling me that I'm selfish. I know, I'm trying to get over my depression and Its hard sometimes and maybe I could be neglectful of myself health wise. But I'm slowing getting better. But he always tells me that he wishes he could tell me off because I have no reason to feel that. That I should be better by now. I don't mean to feel it but he makes me feel worse when he tells me stuff like that. But I do love him and I given up so much for him. I'm even willing not to go for my masters so that we can married and help him get through school (he doesn't qualify for financial aid) Now he says that I was even lying about that. He is always there when I need him, did I really let him down? What should I do? I really love and dont want to lose him. Please advice what should I do? Am I a bad person
