Why am I the Last to Know?

I had a great phone conversation with Kimberly's Maid of Honor tonight, planning the bridal shower, however, it left me feeling very upset and prompted me to write a note to Kimberly. It seemed after speaking with Leah that Kimberly had told her everything about the problems I've had with Mimi. Only problem, I have no idea what Mimi's problem is. My note asked Kimberly to show me some loyalty and tell me what she knows. I am going to have it out with that witch, Mimi, but I deserve to know what's going on so I am not blind-sided. The thing I know: She doesn't like that I won't speak on the phone with her. Outside of that, I really don't know why she treats me so badly and have no clue about what she possibly could say against me. I've done nothing but try to work together, keep her in the loop and try to be respectful. After everything, I no longer feel inclined to be nice. I actually feel like a giant ass for having even tried to be nice to her after everything she's done to me. It is time for a showdown. I have to face the bully if I want any self esteem at all. I will not be able to look myself in the mirror if I can't stand up for myself. That crazy bitch scares me, though! She is ruthless and easily cuts people to shreds at her very whim. I am the opposite of that. I want to just run away and hide until all of this wedding stuff is over. But, feeling sorry for myself isn't getting me anywhere. I've got to be strong. I have no idea whether Kimberly will tell me what I need to know or what I will do if she refuses. I already feel pretty badly about my daughter. I'm extremely disappointed in how she's treated me and how she hasn't stood up for me and her own family. I am so close to just telling Kimberly I will not come to the wedding if this shit continues. I hope it doesn't come to that.
