Sibling Missing Sister's Wedding After Initially Telling Her the Date That Might Not Work for His Family, Internet Debates Who's to Blame: 'She knows it costs a fortune for us to fly out, that it’s a full day of travel in each direction'

When someone you know is getting married, it's supposed to be a joyous occasion. Especially when it's someone in your immediate family. As a sibling, you're supposed to have a part in the big day, too. Whether you're at the wedding party or have another responsibility to help the day go perfectly, as a sibling, you should be excited to attend this big moment in your sibling's life. That is, if you have a good relationship with your siblings, just like this brother and sister do. But he's not attending the wedding, and now he's wondering if he's making the right decision. His sister and partner are in their 40s, have been dating for a long time, and decided they just wanted to have a casual celebration with friends and family. She made sure to sit down with her brother to look at potential dates that he wouldn't be able to make since he lives so far away and has three kids to travel with. Despite her efforts, things took a turn for the worse.
