Made a jewelry list and sent it to my family

My fiancée has made a list of jewelry for the wedding and sent it to my family. Honestly, I was really upset. Sure, these things should be discussed; we need to plan together, but it felt strange to me that she communicated directly with my family like that. My mom also hinted a bit, asking, ‘How much of it should we cover?’ Do you think this is a normal move or a bit thoughtless?
