Pressure

I love my DH I have been with him since HS after 10 years of dating we finally got married last year. My DH want to start our family now and I disagree we are not financially ready.
I am 26 years old and he is 27 years old. I am currently in graduate school FT and working FT. I am trying to get my career started before having children. Right now we can only afford a studio and I hate it. I want a house and I know living here on LI is impossible.
I don't want to raise our children in a apartment. He doesn't care he just want a child he is being very selfish. Before I got married to him I told him once I am finish with my education we can start planning for our family.
I think he is jealous because all three of brothers have children expect him, however his three brothers are not married and they are struggling financially. I try to explain to him about how expensive day care can be and baby supplies and because we are a middle class family now will not be able to get any help because we make too much money.

Please help

Maybe if you wrote it all down what the expenses would be, he would see it and would agree to wait.
