As soon as I became engaged I knew I wanted both of my sisters and their daughters to be in my wedding party. Both sisters as bridesmaids (the oldest as MOH) and the oldest daughter as a bridesmaid and the youngest as a flower girl. I asked both of them right away and was told by one she would attend and the other would have to think about it. That was six months ago, and I am still getting the "I'm not sure yet" from one and the other is saying she will be there, but since I've asked her she has started college and then lost her job and now her car has been totaled in an accident and basically things are just a mess for her. Being it is a destination wedding she has made a few comments recently that she might not be able to afford it. I feel like an ass even asking her again as she has so many more pressing things to deal with.
Neither sister seems to think its a big deal to give me an answer yet, and I don't want to be a crazy bride, but the wedding is 6 months away and so far I have done all of the planning myself with no input from either of them. With a tight budget we had to start planning right away. I hate to be selfish, but I really wanted to have a bridal shower and a bachelorette party and occasional input on decor and dresses and stuff and no one seems to have the time. I am fine planning everything myself, my fiance has been awesome and even suggested a couples shower so we can just plan that ourselves, but I feel really stupid planning my own bachelorette party.
So, finally my question: How long do I have to wait for them to make up their minds before I can just say, forget it and ask some cousins or friends? And then how do I say forget it, I found someone else? Do I send an email demanding a final answer or do I just pick someone and say, "I had to go another way??"
