My sibling decided to exclude my partner from the wedding invitation, claiming they didn’t “fit the vibe.” We’ve been together for years, and I felt deeply hurt by this. When I confronted my sibling, she dismissed my feelings and told me I could either come alone or not at all. I chose not to attend because I couldn’t support an event that disregarded someone I love. Family says I’m being selfish and causing unnecessary drama. AITA? Edit: For those asking for more background: my partner and I are a gay couple, and while my family has mostly accepted us, it’s been somewhat reluctant. My sister is straight and marrying a man, and if I had to guess, she might be worried that including my partner could send the “wrong impression” to her new family. She’s never directly approved or disapproved of my partner, but I think this is part of why she excluded my partner from the wedding.
