How to help a suicidal partner who won't accept help?

@Tofu14 wow this really helped. The second part especially, I was yelling at him about how he never listens to me and how he doesn't make any money and can't budget and all these hurtful things. He is very stubborn and if he doesn't do something perfectly he hates his life. The hardest part for me is when he does this I help him kindly and he doesn't listen for days, weeks and then he becomes so depressed because he "can't figure it out" because he keeps doing the same thing over and over and making sure that he doesn't listen to what I say. I get so so angry and I have gotten a lot better with that but the thing that threw me out of the water was when after I was listening to him tell me about how his family was rich but they didn't trust him with money and it really sucked, he says "I don't fucking care how poor you were. . " I just said fuck you and slammed the door. Some back story, I have 8 siblings and lived in the middle of nowhere in poverty for most of my life, my house burned down when I was 8 and I live in an actual barn until I was 16. And he brings up how is parents would give him money every day to buy food and school supplies but the didn't let him buy anything else and kept track of him and his spending because they didn't trust him. I didn't compare us at all, obviously I had a way worse situation and it took years and years of shitty budgeting and hard times of not eating because I didn't have any money because I was unemployed as an adult to be where I am now. For me to sit and listen to him and then him to stab me in the face with his words is just beyond me. I block him on everything, he comes out of the room and explains himself and its worse, I get groceries and he tells me he wanted to die under the bed. I have dealt with this for the past two years, I became suicidal at one point and had to be more heavily medicated to continue staying alive. I have so much anger and I want to leave him but there are so many road blocks.
