Here's the deal: I can't stand my fiance's oldest sister. When I met my fiance, she wasn't around and his parents were (still are, and forever will be!) raising her children. She up and left them, something that I have had happen to me from my mother. Reason #1 I don't like her. You just don't do that.
Reason #2: she thinks just becasue I'm having his other sister as a bridesmaid, and having her go shopping with me, she's "entitled" because she's his sister. I'm not inviting his middle sister (and bridesmaid) becuase she's his sister, I'm doing it because we're friends!
Reason #3, she's one of those people that are jealous and have to be the center of attention 24/7. I mean, it's fine when you're five, not when you're 30. Right? I'm not saying this because I'm an attention hog, I mean, she can have it! But she just..... bugs the frick out of me. She's very obnoxious.
How do I tell her that just because she's his sister doesn't mean she's my best friend. I'm only having 2 bridesmaids! I'm saving the other spot for MY sister. I don't want to be mean (or get decked!) but I just don't want to include her in my bridal party or the dress shopping. HELP!!!
PS, my fiance is going to talk to her about it, but I know she won't listen, so I have to be the bad guy.
