<human>: My husband, Jason*, and I have been married for 2 years and together for 5. You are probably used to the "he's wonderful" and "he's perfect" posts here....but he is great. He makes me absurdly happy. He makes me smile, giggle, and get all fuzzy. I can't really explain how silly I get when asked to explain.

But.

Two years before us, he lost his older brother, It was a bar car accident. No ones fault. Older man had  a stroke at the wheel and hit his brother's car. Jason was supposed to be driving that car. Instead, he stayed at home. He blames himself. 

Everything bad that happens is his fault, in his mind. I get it. He has guilt. I've told him a million times that his brother's death was not his fault. His parents say the same. But...it's everything. Everything you can think of is his fault. Out of a certain food? His fault. Need to get gas before work? His fault. The house needs cleaned? His fault. 

I've done everything possible to help. I've used every rational argument. Tonight, we drive home from bar and the fact that we had to stop to get gas was his fault. I told him no, I told him getting gas is  fact of life, and he sulked the whole way home. He is still upset about such a simple thing. I don't know what to do. I've told him he needs help, and he rejects it. 

What do I do? How do I make him see that not everything is his fault? He is a wonderful person. Amazing. Just....incredible. And he just can't see his worth.

Note: apologizes. English is not my first language.

Can you give me the gist of the text in a nutshell?
<bot>: My husband blames all on himself after his brother died. How do I make him see that he is a good person?
