Dfriend is Dp's best friend. He is constantly broke to the extent where he can't afford to buy food and his girlfriend has to give him meals (he is also pretty underweight so really needs the sustenance!).
He works full time but is on a low income, has his son every weekend and pays a considerable amount in petrol going to pick his son up and drop him off.
Obviously it is great that he wants to give as much to his son as possible, and I say this as a woman whos ex has paid not a penny in maintainance for his kids but aibu to think he is paying too much if he can't afford to buy food for himself?
