For the most part, do you enjoy your friendship with her? I am in my 50s and regret losing track of some of my friends.

I agree with MickeyCheeky that talking to her would be the best solution keeping in mind that weddings put all sorts of pressures on the bride--sometimes the bride's families expect her to follow their playbook not hers.....
