Partner doesn't want to get married and I'm mad

We are both in our 40ies, live together and have 1.5yo kid. When I got pregnant he didn't want to get married right away but he said we will do it after kid is born. I think that time is now. We were preparing to start working on another baby and I brought it up. Also my mother got cancer and I know this would make her happy just as it would me. But he said he didn't want to think about that now. He said he wants us both to feel happy and relaxed and that he would wish to talk about it then. Which is as vague as it can be. Also he started listing my faults which really insulted me. I'm good enough to live with him and raise his children and have sex with and do lions share of housework but I am not good enough to be his wife. He told me it bothers him that I'm not as rich as him. He would want his wife to have equal assets. Which is also bs. I am hurt, I am insulted, I feel disappointed and disrespected. I am sad and mad. I want to leave. I can't gather up to be happy around my child and it's breaking my heart. What to do? Am I wrong for feeling this way?
