I (18M) am graduating this year, and I’ve been looking forward to it for a long time. I’ve worked super hard to maintain my grades, and I’m proud of myself. My graduation date has been set for months, and my family knew about it well in advance. Basically since August since that's when school started.

My sister (24F) originally had her wedding date for June 7th, which was fine, but then, she moved it to May 10th, which is the same day as my graduation. When she told me about it I was shocked, especially since she literally knew my graduation date or was supposed to. When I asked her about it, she said it wasn’t on purpose and that I already knew she was trying to get her wedding date pushed up some.

I can say she has been trying to get her wedding pushed up for a while because she wanted it in April on her birthday 4/4. But she told us April wasn't available at that time nor may. She said she's been waiting for months and they were able to get the date because someone else canceled. I just don’t understand why she would change her wedding date on such short notice. We knew she was trying to get an earlier date, but we didn’t realize she was still trying to push it up, especially since it was already so close to June so I kinda just expected it to stay that way.

It really doesn’t seem right to me that she changed it last minute and now everyone is scrambling to figure out what to do. I told my sister that I was upset about it when she asked me how I felt. Now she's upset I said I was upset.

My parents were talking to me about and decided that the 'fairest' thing they could think of would be for one of them to go to her wedding while the other stays with me and go to my graduation. Hearing them say that just made me upset because either way someone would be missing it and on top of that I probably know majority of the family probably aren't gonna come either.

I told my parents that I'd rather they both go to the wedding instead of just trying to split it. I feel like I would be hurt more if they split it rather than them just going to her wedding all together. They feel like I'm being unfair and making them choose? I don't see how I'm making them choose? I just told them that id rather they both go instead of choosing one to stay. Either way, I feel like my date was known priors to my sister and mine should take priority...she chose to change it I didn't.
