My (26f) boyfriend (26m) wants me to pay all the rent/bills while he only pays for some groceries

We have been together for 2 years. We?ve decided we want to move in together at the beginning of next year. He wants me to pay the rent and all the bills (utilities, electric, internet) and he only pays for groceries. He makes more than I do but has more expenses than me so I technically end up with more spending/savings money than he does.
I think this would make sense if we were married and truly combined our income but it?s just our first time living together.. even though I have less expenses it still seems unfair that I would pay about 1400 to live there and he would only pay 350 for groceries. He also says I should still set aside about 200 for groceries too so we can buy better quality food.
To me, it seems he just can?t afford to move at all then. He currently still lives with his dad where he pays no rent or bills there. His biggest expenses are his car payment and a loan to payoff from fixing his car and spends about 80 dollars a week on gas. but he insists it makes sense for me to pay that much since we?re a team. but I just have a bad feeling about it. the ratio is just so big it seems like I?d be better off just moving into a bigger apartment by myself. or just stay in the one I have already where my expenses are nearly half of that. Is this truly fair? Is it really a good idea for me to do this?
TL;DR My boyfriend makes more than me but has more expenses so he wants me to pay 1400 and he pays 350 on groceries to live in an apartment together.
UPDATE: thanks everyone for your responses and giving me validation, I definitely have a lot of clarity now!! And I assure you this real and actually happening lol. I decided to tell him these concerns directly again. He was annoyed at me and went on about how I?m overthinking and that I don?t love him if money matters this much to me. I even brought up the situation of it being just a roommate, would that be fair to him? He literally told me he had roommates before where they paid that unfairly. I told him someone was getting screwed over. He?s just disregarding everything and acting like he is absolutely right about it all.
This honestly is really heartbreaking to me because otherwise he has treated me well. He didn?t change his stance at all besides just saying that he wished it wasn?t this way and that if he had more money he would pay for the majority of everything. He keeps telling me he?s willing to do anything to be with me and that?s why he?s so upset that I won?t agree to this. He says the advantage is just the fact that we will be together. Of course I want to be with the person I love but it doesn?t override that it doesn?t make sense and he can?t afford it. I don?t think I will be moving in with him, I don?t know if our relationship will last after talking about this. I really wish we could find a way to work it out. Also, I agree that he absolutely has to be hiding other expenses because it does not add up that he only can afford 350. He told me he could afford 350 and still have 500 left for spending. So actually he wants to ensure that he still has spending money for himself, instead of making it fair. He wanted us to combine our spending money leftover. I feel like he tried to manipulate my emotions so much in this situation and it?s hard accepting someone you trusted and had so much love for would resort to that. Like just be honest, have respect for me that I?m even thinking of this seriously at all. Overall, I won?t be moving in with him anytime soon but I am now pretty heartbroken and have to think things over with him in general.
