Continuation of Sister troubles Rant

I know I may sound like a witch with a b about all of this, but my sister is driving me CRAZY. She called my MOH the other day to tell her that I complained about having my bachelorette and bridal shower in the same month because then I would need to take two weekends off. She then tells my MOH that the bridal shower has been moved to the end of March and that they should just kidnap me for the Bach afterwards. Two of my bridesmaids are in committed relationships with females who will be at the bridal shower. When this was pointed out to my sis, she responded that the “Bach guest list is closed” so now the bachelorette party will be at the end of January instead of the original plan of end of March

A few issues with this all are:
1. I never said anything to my sis
2. My mom and FMIL are planning the bridal shower and never changed it from the beginning of March
3. I already told my MOH and fellow bridesmaids that their SOs are welcome to attend (I am friends with all of them and they also aren’t all into PDA so it won’t get awkward for my MOH)
4. I didn’t want anything in January because of the unpredictable weather here in the Hudson Valley and how spread out my bridal party is (Hudson valley, Bergen County NJ, Syracuse, and new Fairfield CT)
5.she Can’t even attend the Bach in the end of January!

So so now my MOH is ANGRY and has uninvited my sister from the bachelorette party 🤷🏻‍♀️
