Disgusted with one of my BM's

Why do weddings always bring out the true colors in people.

Let's make it short and sweet. So I found out WHEN my shower is but not WHERE. In the same night that i found out when it is, I also found out that this one BM took it upon herself to email all the other BM's telling them that they need to pay x amount of money for the shower.. Keep in mind I have STRESSED I do not want something elaborate.... BUT yet she does not consult my sister who is my MOH. Then i have my girls emailing me telling me what she was doing.. My mother is paying for the brunt of the shower... Her behavior is one reason why we stopped being friends before... I am at the point where I want to just find a replacement for her... Uhhh I need some perspective from some other people.
