So, FH and I decided we just wanted a few of our closest friends and our parents at the ceremony. When I told my grandma this, she seemed agreeable enough and said she would be excited to see us at the reception. Then, a week later, my grandpa died. At the funeral, my grandma asked if now she could come to the wedding.
She's manipulative (ex. She yelled "TODAY IS ABOUT ME!!" at my grandpa's funeral and threw money at my stepsister to follow her around), so it makes sense she would bring it up when I had to say yes.
Our ceremony will be at a waterfall that is a short hike in-- my grandma has a walker and said she would rent a motorized scooter to get up the hiking trail.
I love her, but FH and I decided on this a long time ago. How can I gently reassert that she will not be attending the ceremony but we will be so happy to celebrate with her at the reception?
