I need some advice. I was wondering if it is necessary to have my future sister-in-law in my bridal party. So far I have my cousin as Matron of Honor, My longtime BFF as Maid of Honor, and one of my friends from college as a bridesmaid. I wanted to keep the party small, but now my fiance wants his sister in it too, who I am not close to. I want my 2 brothers in it so I said fair is fair. But my problem is with my future sister in law, who is my fiance's brother's wife. They will be married for a year by the time my wedding comes. Both my fiance and i really don't care for her, we just put up with her because you can't pick your in-laws! Also I am in her bridal party as a bridesmaid, but she is having 8 girls and not really excluding anybody! Help! what should I do!
