My brother decided last week that he is separating from his wife and it is being done in a very cold abrupt way. Him, his wife, and my 2 nieces are planned to be in the wedding and are all aware of thier positions. I have no idea what to do now. His in laws and sister in law have already attended our e party and have std's for our reception.... the original plan was for him and his wife to pull my youngest niece down the aisle in a wagon she is my ring princess.... umm yea thats not going to happen now but im so lost on what to do from here on out. My brother is very close to me and I dont want him to feel un comfortable or feel not welcomed because of her family, he has already stepped down as he has a lot on his plate and i completly understand, do I ask my sister in law not to be in the bridal party now ? Do I not invite his inlaws now ( i dont talk to them outside of him and have never been invited to their family functions that dont involve my nieces) someone please lend some advice im going crazy.
