Baby daddy not helping out

So lately I feel like my baby daddy has been second guessing my baby. He hasn’t did anything concerning her I understand she’s not here yet but every time I ask him to help me get something for her he ignores it or says she’s not even here yet.. Prime example I asked him could he help me out with paying for the baby shower which is for her and never got a answer. Am I over thinking or is he second guessing my baby? I also told him if he feels that way he doesn’t have to come to the shower or hospital until she’s born so he can just get a dna! But swear I’m making him look bad
