I'm getting married June 2013. I have been engaged for a while and we finally deceided on a date. I just found out a few weeks ago that my FI younger sister (21) just got engaged and wants to get married 2 month after we do. It really makes me mad and I think it's just rude. It's super frustrating because I want to be excited and share my ideas for the wedding but I am not interested in hearing what she is planning and I dont want to be stuck being "planning buddies" mostly becasue I can't stand my FSIL. I know this seems selfish but this is my day and my summer and I dont want to share it.
