Im not sure what to think. My sister told me last week she is not coming to my wedding. We are really close, I think this is what hurts the most. FH and I were on vacation, and met up with my Sister and her adult daughter. Sister comes up and says I screwed up. I ask what happened (not thinking it was about the wedding.) She tells me that she bought concert tickets that are the same day as the wedding. My heart fell to the floor. She said she wasnt paying attention to the date when she bought them. So instead of coming to my wedding she is going to this concert. I'm totally heartbroken.
