Advice on money

My bf and I live together and we split the bills. I asked him to get a joint account just to pay bills from and he said no.

He always talks about us getting married so I asked if he would join his finances with me when we get married and he said he wants to keep his account separate.

I don’t know if I want to be with someone that wants to treat me like their roommate rather than their partner.

It’s also hard that he makes a lot more money than me. So when we pay the bills equally, he still has money to save or spend. And I’m struggling.

Any advice
