I totally understand what you mean.Usually when I am pms'ing I feel like no one in my party cares about my wedding. I talked to my MOH about this and she said I was on crack and that everyone has busy lives (family, kids, work) and their lives can't revolve around my wedding. BUT they are super excited to help, but don't know what help is needed.
So my longwinded answer is I agree with everyone on this thread they are more than likely waiting for direction.
