Wow... I can understand your frustration. I'm in the middle of something similar with a long term friend of mine. We've been very close for about 9 years now, and a year or so ago I started making some changes in my life and worked VERY hard to lose a bunch of weight, etc, and it was like all of the sudden she turned on me and started making comments (like yours did with the bridezilla comment)... now that I'm engaged and planning the wedding, I was worried about what to do because she and I are barely talking... but she has always said she'd be standing there with me on my wedding day whenever that was to happen. She is not my MOH but I've decided to cut her from the wedding all together... in fact, her negative attitude and comments has brought me to the decision that she's not even invited to the destination wedding. It's a tough spot to be in... so I get your frustration!! Hope things smooth out for you!
