This is my first time posting but I've lurked on here for years so I'm a bit apprehensive in case I get roasted 
Little back story- a very close (so I thought) friend of mine is due to get married next year. She was one of my bridesmaids at my wedding, she doesn't live in the area but I would still class her as a close friend, we talk a lot!
I got a message from her explaining that she's having a situation with bridesmaids (too many) and would I mind if I wasn't a bridesmaid, but instead she would like to have my dd as a flower girl meaning I get to be with her the morning of the wedding and get to be a part of it.
I replied saying that she mustn't feel obligated to have either of us as a part of the wedding, and that just because she was my bridesmaid I really didn't mind that I wouldn't be hers and never expected to be. But if she does really want my dd as a flower girl then that would be lovely, she would love that etc..
All fine I thought? Until I received the next message.
She said how excited she was that my dd would be flower girl, talked about her wedding plans etc. Then on the end of the message "unfortunately though there's so many children coming, it will just be you bringing your dd and not your two ds".
Abiu to be pissed off? I've told her dd won't be coming to the wedding as it's not fair on the other two (I've been nice about it, I'm not confrontational at all) but I'm so angry that she has basically picked and chosen her favourites. She says there were 30 children and she's "cut it" to 15, and invited more adults to even it out. 
Aibu to think you either don't invite children or you do. You don't ask someone to leave two of their children at home whilst the other is a bloody flower girl?! 
Before anyone asks, it's definitely not an age thing. Ds1 is older than the other flower girl.
