Where do I begin... My FMIL has not spoken to us in two weeks now since she stormed out of our house.
She hates our reception venue (the ones she wanted were too far away or booked)
She hates our caterer (I tried to use her choice but after they didn't return three messages and then the horror stories I heard from friends I went with someone similar and who I knew would be reliable)
SHe hates my dress (which is my grandmother's gown and pre-WWII slipper satin, I'm the 3rd generation to wear it)
She HATES DJs, and we do not want a band.
She's mad that I'm getting silk flowers, even though I am severly allergic to most flowers as is our photographer (my uncle) and our best man.
She won't listen to us she just crosses her arms and pouts and screams at me. I have now been disinvited for thanksgving as my FFIL says its better if my Fiance just talks to his mom alone. Which is fine since I have to work on Thanksgiving.
Update

I didn't end up attending Thanksgiving because I volunteered to work (double time & a half) my FMIL did'nt speak to my FI the entire time he was there.... I attended Christmas Eve Church with them and stayed for a little while after before returnning to my famililes home (our parents live 20 miles apart), she was civil and there was no talk of the wedding at all. Actually there was no talk of the wedding at all until february. We did sit down with her and explained things. She did have a combative attitude at first until I told her our wedding day of coordinator was an aquataince of hers. We have also let her have control of the table and church decorations as well as the favors. She did come dress shopping with my mom and I for my reception dress, and she picked out the suits for the guys. Also, the dress that my MOH will be wearing is one that she pulled for her to try on. Things are getting better with her, as for underlying issues.. well my FI is her only child and she is one of those people who wants to coddle him. Thankfully he tells her no and pushes her away.. though that only makes her try harder.
There is still some feeling of competition b/t her and her neighbors in the small town they live in of who's kid had the best wedding and a little contempt towards my parents as they have the money to pay for everything, she thinks, thought, my parents were in control of everything because they are paying, yet that is not it they gave us the money and said have at it. My FI come from the same area, but from very different backgrounds and sometimes they just don't mesh well.
Thankfully things are better than they were. Thanks for all the advice and just listening!!
