My ex has never paid for clothes, lunches, school trips etc. it's been 13 years or more now. We went to court about something else, and the judge didn't even look at it. It bugs me because it's in a court order. I pay because I want my kids to be happy. But sometimes it bothers me, because on a selfish note as a single parent I could really benefit mentally from a vacation, weekend away, hobby, activity. And there is less money for that because I pay 100% of kids costs. But, such is life I try to focus on the positive of having happy, well adjusted kids.
