Am I being too much??

So I was in foster care growing up, and now that im over 18 i am in ab12 im currently 19. Anywho, i get $572 a month ($286/every 2 weeks) and also for my son $900 ($450/every 2 weeks. Well, my man doesnt help me with anything, just worries about his own self, he gets paid $850 every week!!!!!!! I asked him for $100 a week and he said im doing to much, so then I said $50, which is something. I said since he doesnt help me I want money for his son, i wanted $100 a week so i can save for a month so i can buy things he needs especially clothes because he grows fast... am i being too much? Or am i reasonable

Mind you: i pay $300 in bills monthly, and i pay for groceries which is up to $100/weekly
