My sister is getting married this weekend, and while part of me is happy for her, most of me is dreading it because I don’t think it’s the right move. Some necessary context to help you decide if I’m wrong here - 

I’ve never liked her fiancé, even before they got together. I was vocal about my disdain, up until they started dating. Then I backed off completely with my outright dislike of the guy but I have to admit I’m cordial to him at best, and definitely not friendly. Now to the actual question. 

My parents are not good at planning parties. Her fiancé’s parents are far away. My MIL is wonderful at party planning and is a saint, so my own mother asked her for help. But my MIL and I live a few hours from them. 

For the past 4-5 months I have been transporting wedding items back and forth from my parents’ house to my MIL’s house. I travel for work, so sometimes these transfers have taken place during my work trips (which isn’t out right prohibited, but it does make me feel sketchy. Which I expressed to my mother and she blew me off). These trips aren’t super often, but probably one or two every other week. 

Now the wedding is three days away and there is still a lot to be transported. I have already volunteered to take off work Friday and drive down really early in the morning to get everything there. The wedding isn’t until Saturday. My sister just texted me on behalf of my mother asking me to leave work early on Thursday as well so that I can get there sooner and make sure we have everything we need. 

I really don’t want to do that. I’m taking my vacation time for this already. And I’ve already taken lots of time out of work to make trips for them. I want to tell my mom (who works from home) to make the drive herself tomorrow if she wants everything there so soon. But I am having a hard time deciding if I’m just being really selfish and mean because I already don’t want this wedding to happen, or if they’re being unreasonable asking me to leave work a day and a half early for items they could have retrieved themselves much sooner. 

So, AITA?
