I do EVERYTHING!!!

So I have something to get off my chest that I have been stressing for a while and I need advice on what to do hopefully somebody can give me some insight as if they may have been through something similar to situation. So my husband and I have a system as to how we operate when it comes down to our finances he pays the mortgage and his car note and insurance and personal bills and I pay the utilities and personal bills. But we share the responsibility for the needs of our son. But every time I ask him to get something for our child he act like he can’t do it or pulling teeth to do it and says he never have any money but then he buys things that he want for himself or says he saving money. Almost everything that our son has I have bought. Every time I’m out I always make sure our son has or if I knows he needs something I will go and get it cause I can’t really depend on my husband to get it. Then he complains about something’s that I get for him but he doesn’t contribute to our child financially outside of saying he provides a roof over his head. Last time he bought anything far as clothing or shoes or daycare was last November.🙄 I hold him responsible all the time but I always end up doing it cause I can’t count on him to follow through or it’s always a attitude about it or try to cheat our son out of things cause he wants to save money I feel like for personal things he wants. I just feel like he relays on me to do everything for our child so he doesn’t have to do anything . I’m just so frustrated
