We got engaged in 2019, to be married in 2020, postponed to 2021, postponed again to 2022. My mother was at once given a plus one (on the first wedding date), but we have since made major cuts to our guest list including her plus one.
My mother is not contributing to our wedding day at all, and yet still insists that she gets to bring her best friend as a plus one (because she's the mother of the bride). Her friend is someone I have not had a relationship with for 8+ years, and my Fiance has only met once for <15 minutes. My mother will be busy with Mother-of-the-bride duties which means her friend will just be hanging around doing nothing anyway. My mother has been continuously harassing us about this for days now. We already have a strained relationship and no one else on the guest list has a plus one (everyone has an invite by name). AITA? What do I do here?
