I'm a BRIDEMAID for my sister in laws weddin, and she's been doing a lot of stirring between her friends and me! I am really upset with her becoz I found out a lot of hme truths when we went on her hen weekend.. she is also tried to get money out of us like saying the hotel was 30 pounds and it was only 25 pounds. And some of her mates don't know about that! And for my hair trail she said a regional 15 now she's saying 20 pounds. I don't know what to do becoz its my husband brother she is marrying and they have children already if I fall out with them I might not be able to c them. WAT SHOULD I DO? ITS ONLY 3 WEEKS TO THE WEDDING?

Luckily the wedding is but for one day.
Fulfill your obligations as a bridesmaid since you have already accepted. After that, you are not obligated to her anymore.
Let her have her day, let her have her way, then just let it go. It doesn't look like she's bilking anyone out of ridiculous amounts of money, and not worth squabbling over or causing a huge rift.
In the future, if it still bothers you, think twice before doing her any more favors.

Thank you I Think I Needed That Frm Someone Else!!
