Having a baby

I want to have a baby with my SO. But he been very different now... He will get mad if I ask how much money he has... What he does with it, about his work... Little things like that, will make him get mad if I ask... Today I got very upset because we need stuff for the house.. & we needed some soap... I told him we needed that.. And he told me.. For what? You already got some body wash, you don't need body soap. I got upset.. He can't even buy us that.... I'm starting to think its not a good idea to conceive with this kind of man.
