Sorry, I'm another one who thinks YABU.
I had 2 bm's, both good friends. We went out 1 day, spent an hour choosing patterns/ material for their dresses, then the next few hours supping cocktails (nearly left the material for the dresses on the train on the way home
) They then organised their own dressmaker (one of the girls' mum's made her dress), arranged their fittings (I suppose) to suit themselves, I had nothing to do with it- I trusted they would come dressed in something on the day
They chose their own shoes (but as they were my mates I would have known their shoe sizes anyway- we'd borrowed each other's shoes enough times)
One of them organised the hen night, and did a brilliant job of it, because she volunteered to do so. I was delighted. If she hadn't offered/ wanted to do it, I'd have cobbled something together myself. Have to admit, that bm was pretty proactive (she has always been the organised one of us!) and got involved in flowers/ my going away outfit, other bm wanted to come with me to choose my dress (which took a whole 2 hours. Then we had cocktails...)
Actually, we had a lot of cocktails, and a lot of fun. I never ever expected the girls to get so involved, and was really touched with everything they did. But I didn't expect it, and would not have demanded any of their time, never mind 2 weeks!
Also I never ever got this "my day, me me me" thing. My main focus of my wedding was the reception, making it fun and relaxing for my guests, welcoming people who had travelled and making sure everything was tailored around my ill mother. My biggest priority was getting her oxygen generator to the venue and ensuring there was disabled access. the joy of my wedding came from firstly the ceremony, where I got hitched to my DH, and then seeing all my friends and family enjoy themselves at the party.
IMO a wedding is about everyone. A marriage is about 2 people.
I do think you need to take a step back. If she is your friend first and foremost, who cares how "into" being a bm she is? There will be many times in your life when you actually need your friends. Your wedding isn't one of them
