So I don't think I'm being unreasonable but happy to be corrected!
One of my really good friends (I am a bridesmaid) is getting married this year and the hen do is at the end of Feb. Her maid of honour told me the dates it would be some time ago. I explained that I would have to leave on the Saturday night as it is my dads 50th birthday on the Sunday so obviously can't miss that obviously wouldn't expect the dates to change for me but also can't change the date of my dads birthday. Was told this was fine.
I kept asking if anything needed to be done or if I could help in anyway and the maid of honour said it was all in hand. Kept asking for more details but got nothing back until yesterday. Saying I needed to give bride 180 pounds for accommodation for 2 nights in Brighton! I said that's a lot of money and asked how much the activities would be on top. Bride called furious saying that I shouldn't stress about money!!! And that I knew about the weekend for ages (but no finer details such as ones or location until now) and I'd already gotten out of half the weekend which has upset her. I said its really not a lot of time to expect people to get that sort of money together and I would struggle to do this and also pointed out I'm not actually staying both nights but still expected to pay for both so that it doesn't cost others more. I'm really annoyed and have no idea how I'm going to get this money together. This is so unlike my friend to be like this.
I know If I mention the money again she'll go off on one again
