I 24F and bf 24M keep arguing about money. Is this something that can be fixed?

My bf and I are about to move in together into a condo style house that my parents bought years ago. It’s 3 bedrooms and we will be having a roommates save money. We are splitting rent making it about $450 each, which is super cheap bc we have the other roommate. He makes about $4000 a month and I don’t have a steady income (I’m a bartender and full time student) so I maybe make about maybe $2500 a month. The problem is that I have more money saved up then he does. I’ve been working since I was 15 and his parents didn’t let him get a job until 18. I’ve saved up a lot of money in this time. He also has a loan for a motorcycle and truck that is about $1500 a month together. I don’t have a payment to make on my car except insurance. Since I don’t have a lot to pay for other things he tells me that I should pay for the things I thought we were going to split. We need a new dresser for the condo, he says that since I have more money saved that I should buy it and it doesn’t need to be 50/50 all the time. I don’t think this is fair. He thinks it’s fair bc I have the money and he doesn’t. I told him that he needs to figure out his finances bc he makes enough that he should be able to do 50/50. He gets mad everytime I bring that up and it always turns into an argument. I don’t want to break up over money but I’m scared this will lead to financial problems down the line. I plan to marry him one day but idk if this is a make or break deal. Has anyone been through this before? Is there any advice please??
