I am recently and happily engaged! I've asked my future sister in law to be one of my bridesmaids, because it is important to him to have his family be apart of the wedding. I've also asked my own sister, and several other very close girlfriends of mine to be in wedding. My issue now is the bachelorette party. My FSIL is a very difficult to say the very least. My fiance says, as a rule, if you're around her for 24 hours, at least one hour will be a temper tantrum. She's incredibly self centered, and can often be cruel. For this reason, I don't want to have her at my bachelorette party. I don't trust her not to make the weekend about herself, cause drama, or be unkind to my friends and the last thing I want is to get into a screaming match with my FSIL 2 months before the wedding. Do I have to invite her? She is almost 10 years older than myself and the rest of the bridesmaids, and doesn't really drink or party (while I'm the first of my friends to get married and have a pretty wild group) so I'm hoping that's a good enough excuse to not invite her, without feelings being hurt.
