So we've been engaged for 2 years and our wedding is coming up in September. I should have nipped this in the bud a long time ago, so I am more than prepared to take responsibility for that, but now that it's getting so close to the wedding I don't know how to handle it anymore!
I'll start from the beginning... So when we started planning, I asked his side and my side each for a list of 60 people that they wanted invited. My fiance and I were each going to invite 20 friends, leaving us with a hopeful guest list of 120 max. His mom handed me a list of 100 guests, and insisted that they all had to be invited. When I told her that we did not have the budget for that, she crossed 5 names off the list, gave it back to me and insisted the remaining guests (a majority of whom my fiance and I do not even know) were very important and could not be left out.
So then, his mother insisted that his sister be my bridesmaid, which I obliged, but every step of the way she has been changing things, not liking the jewellery I picked out, right down to having a bridal shower at my house! (Which I advised them, in no uncertain terms is tactless and I did not want, they planned the whole thing anyway and told me the date).
Most recently, his mother told me she needs to give the seating chart a "final approval" before I am finished and I'm completely fed up. It's MY wedding! I just don't know how to tell her that without ruining our relationship. And it's much too late to change my mind about his sister being a bridesmaid, but is there anything I can do to tactfully get them to step off? Any advice would be helpful!
