My MOH is also my FH's sister and my BFF. When I asked her, it was purely for the reason that we are close and I didnt really think anyone else would really be suitable.
I had planned to pick dresses out online and have them ordered but she wanted the excuse to shop with me so we made an evening of that, dinner and crafting. I wanted a simple $100 dress but she picked out a $200 dress. I didn't mind because she is the MOH and the other two could still wear the dress I originally picked out without clashing. Then she had me pay for dinner because she had spent so much on the dress. Between that and owing me nearly $500 for babysitting (I wouldn't even care as I don't do it for the money but she keeps bringing it up), I was a bit annoyed. I still paid for her dinner because I didn't want to be ugly with her.
I did not, when I asked her, expect her to plan anything, especially as she has two children, a full time job and leads a group (volunteers). That said, she then volunteered to host a bridal shower (if I wanted one-I declined), the bachelorette party and handle night before arrangements, She also said she was super excited about doing it. She hasn't been in touch at all with it and when asked, says "I can do that" but has done none of it. She did book our room for the night before. I was originally planning to do it all myself so its not the idea of doing it that is bothering me (I don't even want anything fancy). I'm worried that she's going to wait until last minute and not find a place for the bach party. We are 5 months out. Should I take it over myself and plan it or am I being too impatient?
EDIT to clarify: biggest concern at this point is that she hasnt asked for a guest list and therefore I know people havent gotten save the dates. Since its a week night, i'm worried they wont be able to get the time off.
