Self Centered Bridesmaid

Hi ladies, I know that there has been lots of drama and lots of people leaving these forums, but I hope that I can still get some reactions and advice. This Sunday, I went with my four bridesmaids to buy BM dresses (along with my mom and sister, who is my MOH). I love all of my bridesmaids dearly, but one girl was SO obnoxious the entire time and really sort of ruined the whole experience for me. She got married on NYE (I was her BM) and spent the entire time at brunch talking about herself, her wedding, her upcoming honeymoon, her her her and barely letting anyone talk about anything else. Then, when we went to the dress shop, we were looking at the racks and trying to see what dresses they had, when she drags me into the changing room with her, strips, and has me helping her get into and out of dresses - not letting me be with the rest of the group or look around. She then found a dress she liked and refused to try on more, while still demanding all my attention. Cont. in comments...
