so i have had a problem with a bidesmaid of mine. we got engaged about a year ago and as soon as we picked the date i asked my girls to be bridesmaids so they all had about 10-11 months notice. for simplicity sake lets call her bridesmaid "A". Me and "A" were really close but as soon as i asked her to be a BM she fell of the face of the earth. in the last 10 months or so i have gotten ahold of her mabey 4 times. its starting to get to when the girls need to put their half of the money for thier dresses down ( i paid the 1st half they are all custom their half is $75) and again i can not get ahold of BM "A". my bridal shower was yesterday and she didnt show up and when i called to see if she was ok there was no answer. she posts a gazillion posts to Facebook from her phone everyday so i know she has it on her. On top of this it was originally her or my sister as a BM. At this point i would much rather have my sister at my side then BM "A". is it aproperate to ask her to step down. im super stressed and frustrated. thanks for listening
