Rsvp from guests

Forgot to add: after discussing with my fiancé last night when she changed the rsvp, he really doesn’t want her to come at this point.

In this situation, I would invite her if she's someone I trully wanted there but I wouldn't if she's someone I only invited because she's family or if your parents or other family members pressured you... and if I barely see her and I wouldn't mind should she decline.
Whatever you decide, I totally understand your groom's feelings because her behavior is odd, to say the least.

" I asked her to please wait until May 7th (the date listed on my rsvp card) in case anything else comes up": It says it all !! I'm not sure whe she RSVPed, then "unRSVPed", then "RE-RSVPed". I could get should she tell you: "I may come/not come but I will confirm this later" but I wouldn't do what she did.

She guilted me into inviting her in the first place. My fiancé and her have said maybe 2 words to each other since i have been with him, and he has never met her fiancé (I personally am not a fan of her fiancé, and he does not like me much either). My fiancé told me to tell them not to bother coming at this point. We are having a very small intimate wedding of about 15 people.

View Quoted Comment You only mentioned reasons against inviting her and her fiancé but I son't see any "for".
Plus: weddings that intimate generally includes immediate family and closest friends you're still see in-person on the regular or via the internet.

What I am dealing with the RSVP cards is that some guest are telling that they sent it but I have received there's because I have a list with the ones that I have received. And then I told them verbally and thru text that they have an extra week from the date because of out of towners. I have return wedding invitations because of wrong addresses
