Will I be accountable for my husband’s riba-based choice?

Salam alaikum, I’m really struggling with something. My husband is planning to take a car loan and honestly, he doesn’t seem bothered about how serious riba is in Islam. I told him it’s haram and I don’t want him to go through with it, but he just says stuff like “most Muslims here in the US have no choice, so it’s just adapting to life in the West”-which I know isn’t true at all. I’m worried: will I be getting sins just for seeing this happen and not being able to stop it? I so wish he wouldn’t take this path. I’ve tried talking but he won’t listen. Also, does anyone know how hard it is to get financing from an Islamic bank? I keep thinking maybe we can look into that instead. Any advice or duas would help.
