You didn't answer the questions. Your answers will make a difference in my opinion on the subject.
When my husband and I were NOT working as partners with regards to the kids and the house I would get extremely resentful. It wasn't because he had activities and meetings all the time, it that I felt like I couldn't count on him in an emergency. When we both made a concerted effort to really work as a team, things improved 200%.
I'm not sure keeping it to yourself is such a great idea. However, it can be a topic for discussion. What would have made him NOT give such a quick "no" response? Was there a better compromise that could have been worked out instead? It's not like your kid is sick and throwing up every day.
