Advice on how I (30F) should handle difficult situation with my mom (65F)

A few months back I became engaged & since then things have been a bit weird with my mom.

First she seemed super excited about it but has since started withdrawing since I started planning the wedding. She has made it clear that she thinks weddings are a waste of time & that it is an *inconvenience* for guests. She basically wants me to have a courthouse wedding.

Now since I have reserved the venue & started making arrangements she is beginning to make comments about not knowing my groom very well. Which is true 😅

My mom has been very emotionally distant most of my life & doesn’t bother to join in my interests or make time to do things with me. I’ve tried to invite her but she always has an excuse, which makes it difficult for her to get to know anyone involved in my life 😅

Any advice on how to handle this?
