So I got engaged early July 2024 and just chose our venue and date this past weekend. I have a grandma who messaged me asking who I'm putting in bridal party and more specifically who my flower girl is. I am having my fiancé's neice who is 3 be our only flower girl. My grandma has another granddaughter who is 7 (she is my cousin) who she wants as my flower girl and I do not. I am not close with this cousin but my grandma helped raise her. So my grandma blew up on me saying I'm ungrateful, a mean person, telling me it would mean a lot to her to put her in as my flower girl etc. Really made me feel like crap but I'm not budging on my decision.
Thoughts? Am I a terrible person like she tells me I am?
