So my mum is married to my stepdad- has been married for 35 years so been in my life since I was 3/4. His son is getting married. Small wedding at a very expensive place- not really relevant apart from the size. My mum and stepdad have obvs been invited, me and my biological sister haven’t? What’s even more strange is my brother- son of my mum and stepdad and half brother to groom hasn’t either? No family feud, no explanation nothing? So basically AIBU to be upset that I haven’t been invited and even more so our brother hasn’t?
