He seems lazy and not pulling his weight. Especially as you identify this as a pattern from him towards you and your son.

It would not have cost him anything to get an item that he and the family (even if you weren't going to eat it) would eat, except some energy. He is a grown man. Taking care of the family means not only working for a paycheck but also ensuring the family's needs are met - and that includes grocery runs. His being tired is not an enough to excuse his laziness.

Men like him use the same old, i.e. oldest excuse in the book, of deflecting and projecting their own 'failures' by accusing you of being the problem e.g. 'nothing I do pleases you'. Typical textbook excuse.
