so I have this friend who we've been really close for over 4 years (all throughout college) she's a little crazy but she was usually a good friend to me. The past year or so though she's been very manipulative over our friendship. She gets mad when I hang out with other people and constantly bad talks all
of my other friends to our mutual friend (who happens to be my roommate) she even told my roommate that she would be so pissed if my best friend ended up being my maid of honor and not her. Fast forward to when I got engaged, she told me her boyfriends sister (who she has never met) was getting married on may 12th but that if I ended up picking that day she would obviously come to my wedding and it wouldn't be a big deal. A few weeks ago I end up telling her we picked a day and it's May 12th, she abruptly left my house and made rude comments about how my dad is saving money since she won't have a date. She proceeds to call me that night and tells me to change my date (knowing we have booked vendors and our venue) or she wouldn't be there. The next day I text her and say that we can't change the day but I encourage her to go to her boyfriends sisters wedding if that's what she needs to do. She then apologizes once she realize she can't manipulate me into changing my date. Bottom line: she's a super toxic friend and I've been trying to cut it off for a while now. Idk if I should include her in my wedding or not. I haven't spoken to her since this whole event but I'm genuinely scared of what she might do if she's not in my wedding (she can be genuinely crazy at times). But I'm also afraid she will try to sabotage my wedding since she hates all of my other friends.... please help I have no idea what I should do
