I can’t believe

My boyfriend of three years think I’m evil or turning my back on him because I didn’t wanna get a car to share with him? We both got taxes and in fact he got more . I sold my car to get me a newer car and he has a car & plans to sell it after he fixes it , but thinks we should share a car. When we both need our own car and in fact we are not married we are just boyfriend and girlfriend and if we ever split someone would end up without a car , it’s just a headache. I think both people in a relationship should be bossing up themselves and not rely on the other person . Please I need advice , only thing he keeps bringing up is this car and how he doesn’t look at me the same and plenty of times I go him “ HE CAN GO “ we live together but it’s in my NAME ! So BYE . Tired of putting up with someone 31 and acting like a child. I’m 21 years old for god sake.
