@Jimdandy that reminds me of MIL and our wedding. CFer nearly got herself uninvited and banned!
DH and I were paying for it ourselves with £1000 gift from my mum and stepdad and £1000 from my dad and his wife.
To keep it small I said I wanted our 2 DDs as flower girls and my DSis as MOH only (to help direct my DDs). Mil went mad insisting I have SIL and DH's 2 nieces (who refused to refer to me as an aunt even though I had been with DH all their lives). I told MIL I couldn't do that or I'd have to ask my DNs too making it 9 bridesmaids. She said I shouldn't have my DN's, only DH's DNs.
Foot went down. Nope.
MIL refused to buy an outfit because they were too expensive. She threw a huge tantrum that my DM had a nice MOB outfit and she didn't but still refused to buy one. MIL is loaded. My DM had to scrimp and save. She threatened to wear her black work trousers and a shirt if we didn't buy her one. She refused to buy a secondhand one.
No. Foot down again.
She ended up buying a nice one. However, whoops! I forgot to disclose to her that the boutique I took her to, 2 days before the wedding, selling cheap outfits was in fact, second hand. She thinks she got a bargain.
MIL's friends owned our venue and were catering it. MIL actually fucking cancelled our evening buffet so that her friends could attend as guests. It was a couple of weeks before the wedding!!!! When I asked who would be making our food she shrugged and told me my DM and aunts should do it.
My entire family were travelling from the other side of the UK, most a 5 hour drive, some an 8 hour drive. MIL and her family however lived local.
I re-booked the caterers but did remind them that they were more than welcome to come as guests and to leave their staff to it. (Which is what would have happened anyway)
Mil asked what kind of vintage car was picking them up because she wasn't getting in just anything. Same goes for DSIL and her family. I said we couldn't afford wedding cars and DH's and mine was a one ride wedding gift from a friend with a vintage car. She threw a fit.
She also wanted us to hire a bus to pick up all her evening guests family who were local, many within walking distance (small village) and a few from the next village and to drop them home again afterwards. From our tiny budget there was no way we could afford to transport any guests. They were invited and would be fed well and even a few drinks provided but we weren't picking them up too!
MIL realised that as a few of her siblings didn't want to come (DH wasn't close and MIL is.... grating), that my aunts and uncles now outnumbered her side. She demanded that I uninvite members of my side.
She also insisted that HER aunts and uncles be invited. People DH didn't even know. DH said no and she said "Why not?! Quayboard's aunts and uncles are invited! Why shouldn't mine?!" DH reminded her that as the bride, mine should be, just like as the groom, his also were.
She put in orders for corsages and buttonholes for her side of the family and we had to pay. At £10 each it added £100's to our flower bill and she didn't even wear hers because she doesn't like them.
We were only intending on buying for the wedding party, not the rest of the guests. My side bought their own if they wanted them.
All this and she knew we were paying for our small, low key wedding paycheque to paycheque and on credit cards.
I almost called the whole thing off a hundred times, all thanks to MIL's demands. There were quite a few more but my post is too long already.
