money problems

My bf keeps telling me I spend my money on stupid things which is my necessities as a woman, I buy groceries but he says I need to buy more groceries bcz he's tired of doing the paycheck to paycheck thing. I work and he does too but I believe he is giving too much money to his parents, sometimes we literally don't have anything to eat. He also wants me to start putting in more money so that he can give his parents MORE MONEY. He wants me to pay most of the rent and buy groceries and buy my necessities out of the little I make. He is also helping his father payoff a loan he made but I'm really frustrated that he lefts us without to give to his parents. They are not old and he has two grown ass adults(brother and sister) to also help them but they don't. Everytime my bf goes over he has to take money to buy something they want. I don't mind him helping out his little sister but the rest I don't appreciate. I hate how they use and abuse my bf and he does nothing about it. They.always want but can never help him. Everytime he asks for a favor they are too busy.
