I feel like my mom's being a little insecure about things, and while I err on the side of not caring and letting stuff slide, it's like she errs on the side of assuming something's a slight.
Most recently, my fiance's mother (we're getting married this June) told me that her best friend (let's call her Peggy) offered to make corsages for my fiance's mother and aunt (who's almost like a grandmother to him), to save my parents money. My reaction was, Okay, that's weird, and they won't match, but okay, thanks, I guess.
(Peggy's actually a kind of pushy person in her own right. At my engagement party she introduced herself as "the wedding planner". She and my future MIL used to have a catering business together, and still do flower arrangements/decorations and food for wedding receptions, so they're both fairly confident about making corsages and the like.)
Now when I told my mom this, to remind her to tell the florist we're getting, she was kind of affronted. She saw it as rude of Peggy to offer to get corsages....but only for the groom's side (her best friend). Supposedly, something similar like this happened at Christmas-time, when Peggy was throwing my fiance and me a shower at her house. Her son had done our engagement photos, and Peggy had framed a large one for the party, and then she announced to everyone that she was giving it to my future MIL. My parents were pissed about that, since they're the parents of the bride, and if anything it should be equal.
So, my mom is stressed out because she sees this as another way in which my future MIL is trying to separate the two families and make herself stand out (she hangs out with a pretty ritzy crowd, who all have huge houses and all their families have lived in the same area for generations). She also is jealous and feels that that my future MIL acts in a way so that she is always very sweet and then she gets her way.
So, I'm just trying to make it through the wedding. I have not at all acted like a bridezilla, and I kind of wish I had, just so I could be the one causing the drama instead of dealing with it. I told my mom I would call my future MIL and tell her to tell Peggy thanks but no thanks, and that I really would rather all the corsages look the same/like they were made by the same person.
What do you think, and what would you do about this situation?
