I'm planning on having my bridal shower on a Saturday morning and my bachelorette party that evening. A lot of my bridesmaids/friends have busy schedules/will be traveling for this so I thought it would be easier if they only had to plan around one weekend. In my haste to coordinate with my MOH on my bachelorette party and my aunts on my bridal shower, I totally spaced and forgot to run the date (July) past my future mother in law. When I did tell her, she was very upset that I hadn't run it past her and it turns out she has a church commitment that weekend. My aunts already put a deposit on the bridal shower restaurant and the weekend works for literally everyone else. Obviously it's important that she's there too but at the same time, I don't want to reschedule so I'm at a loss for how to proceed. Any advice would be appreciated!
