Buying A Car Together, but he’s fucking me over?

My bf and I have decided to go in on a car together since his credit is better than mine. We live together and split all our bills. My car broke down and I need a new one so this is really my only option.

I want to get something used, something with 3rd row seats because I have 3 kids. He says he wants to get a 2019 Malibu.

My current car is a Chrysler and I know that it’s small and hard for all the kids, they’re all in car seats so it gets tight back there. I explained to him that a Malibu isn’t really a good option nor does it cover anything we need or want. It’s not the right fit for our family.

I know it’s his credit but we’re trading in MY chrysler to get this new car, if it were his car we were trading in, I’d let him choose the car he wants. But this is a car I’ll be paying for, my name will be on too, and my kids and I will driving in. Plus I’m giving up my car for this.

Well he made the comment this morning “lets just get the Malibu, and in a year I’ll take over the payments and keep the Malibu and you can get a different car”. So basically I get to pay a years worth of payments for him and then start back over. Which makes no sense to me. I could get the car I want and save myself money and time.

I feel like I’m being cheated right now and I feel a type of way about it. Am I not thinking rationally or this dude trying to fuck me over?
