How can I help ???

My husband has been extremely stressed over the car I crashed. He had only had it for a couple of months when I got into an accident. Thankfully my insurance covered it and we took it to a body shop my husband picked out. We just got the car back and there’s now mechanical issues with it, the car keeps turning on and off. By the way, we’re talking about a Bentley. I work a minimum wage job as a sales person and I earn commission only. I don’t get paid much and each time I’ve tried to grow with the company my husband doenst support me. He says I should stay a sales person because my schedule is very flexible and I’m able to spend time with the kids. If I was to become an assistant at Nordstroms (my job) it will take up all my time. Our lifestyle is a bit crazy so becoming an asssisant would be hard for me. Now he’s stressing out about this car, our bills, and I have no money to help out. I feel extremely bad and he’s mad that he has to figure it all out on his own but I don’t know how to help him. He hardly talks to me because he’s Overwhelmed with everything and when I ask him what’s the matter he starts to talk about how stressed out he is about all the stuff he needs to pay. Like rent, car payments, he also just bought a company so he pays $1500 monthly for it. And he pays child support for his other kids which is also around $1500. He has major bills and he’s always paid them himself because again, he doenst want me to get a job that requires to much of my time since he wants me to spend time with him and the kids. But then he gets mad that he has to figure this out on his own. How can I help him? I can tell he is mad at me for crashing his brand new car which was suppose to be fixed but when we got it back like I said, now there’s mechanical issues going on. He said I should call the insurance and tell them what’s going on. Do you think they’ll help? We already got the body fixed, but the body shop doenst do any mechanical stuff so now we have to take it to a mechanical place.

Also, he does earn really good as he has a construction company so he can afford things but he doenst know how to save

Money. When I say anything he says I question everything and I’m annoying and he doenst touch my money at all.
