I am having a destination wedding in February of 2016. I asked several of the girls invited to my wedding to be my bridesmaids, including Fi's sister, my cousin, and two close friends. They all said they would be thrilled to be in the wedding party and would always talk excitedly about the trip. I tried not to bring the wedding up too often, since I knew a trip to Maui would be a large investment and also made sure to tell everyone not to feel pressured to come and that I was completely understanding if the trip would be too much. Now we are getting closer to the date and have sent out invites. One of the friends who was supposed to be in the wedding has not contacted me at all in the last month, despite previously saying that she was planning to book a ticket and hotel shortly, and has not responded to my multiple calls and texts. Should I assume she can no longer make the trip? I am at a loss, because we typically talk every week or two and I can't understand why she is ignoring me!
