And yes, I can relate to the - never has enough - of whatever issue. When I got my oilfield job I started paying my at the times wifes credit cards of I would pay off $500 and she would then spend $600 before I made the next payment and this went on until I just gave up and let her have her own bills again. She wasn't happy but at least I was and that was better than nobody being happy.
So yes, no matter how much you give, it's never enough with some people.
