Was this girl wrong to block me on Facebook?

This girl who is a friend of my friend was planning an outdoor event with friends of friends and all my friend invited me for her. He told me she knows I am coming so all I did was send her an innocent message and just said something normal like:” hi there, my friend told me about the event and he had said to contact you about it. I was wondering if you would like me to bring anything?” Then not only did she never respond, but she BLOCKED me all together on Facebook. It was very rude. I asked my friend about it and he just told me he didn’t want to get in the middle of it and now I feel awkward even wanting to come to the party now because she blocked me.

Was she wrong here?
