So today we are going dress shopping for my mom. My MOH who is also my sister keeps saying that she wants to be home by 2pm so she can hang out with her boyfriend that she is living with. She doesnt work the weekends unlike my mom and I. I am completely fed up with my MOH giving me deadlines of when we have to be done a task that is not benefitting her. She is annoyedThe whole way through she has been uncooperative, and I have been bending for her. For the BM dresses she told us that she could only do it on a certain day after 3 pm- which was a sunday, she could care less that one of the girls had to drive an hr and a half to get there and back. If I approach her about the issue that she is being selfish she says I am a b**** and just wont help with anything then ( not that she does anyway. This is the same one that assumed the role of MOH and got in a physical fight with me over me wanting to "talk about the wedding too much". I wont even bring up anything about the wedding around her because I know how she gets. Besides that, It is my moms day to get a dress and she should have all the time she needs. How do I confront this issue?! I won't dare ask her to do anything ( I have been doing everything by myself) because I have flash backs of the fight we had. I am even afraid to ask my other girls for help. Even trying to find places that are open on a sunday she wasnt even willing to help try and find anything in the area for my mom- she told me to call around.
