I am getting married in October of this year and have already sent out my invites to all I considered friends. One friend unfortunately has voiced her opinion many times on how she thinks I am moving to quickly (though got married a month after knowing her husband) and doesn't like my fiance. She's also very childish and immature, kind of stuck in the high school-like lifestyle. After much thought I've decided I don't want her at my wedding, as I only want people there who are truly happy for me and support me in this. Is it bad etiquette to uninvite her? What is the best way to uninvite guests you longer want there?
