What do you think me asking my boyfriend to pay for some of my car maintenance?
Why do you want to ask your boyfriend to pay?
Because I can't get over the fact that he has more money than I do.
It can be tempting to ask somebody who has money for help but you shouldn't do it. He might think you are a gold digger if you ask for money for things you need to pay.
What he doesn't know won't hurt him, besides he owes me since I help him with his bills and he has some savings.
Car insurance is a personal expense and you should pay it yourself.
