Disrespectful daughter and son in law

We have helped our daughter and husband both physically and financially, even though the husband earns over a six figure sum. What with the school holidays coming up I had offered to help 2 out of my daughter's 3 day week. Also, school pick ups to our house, which I had been doing for the last year. Within a message she said that she longer require our help and has arranged alternative child care. I know that my daughter is doing this as a form of revenge as she knows that we are not happy with their lack of respect, moreso her husband. I 've made no comment but am deeply hurt. My daughter is difficult to talk to. Losing her yemper and crying. Should i say something or remain silent?
