Am I being dramatic?

My boyfriend and I are buying a car Friday. He’s paying for the down payment and such. But we initially agreed both of our names would be on it, and our car salesman said that we could. But now, we just got in a huge fight bc he only wants it in his name bc he said all of his family told him to basically cover his ass just in case we break up and also that it’d help his credit. I want my name to be on it so he can’t use it to control me by saying something like “well it’s my vehicle, your name is no where on it” or something like that. He got yelling mad over it. Like why can’t both our names be on it and help us both out? Why does he only get to be the one who has his ass covered? It isn’t fair. Am I being dramatic by feeling so pissed off and hurt by this?
