My older brother got married this summer. We have no other siblings and have always been close. He paid tribute to his wife, their daughter, our parents, his wife's brother and two of his close friends in his wedding speech but there was no mention of me. I was hurt by it at the time and he came to me afterwards and apologised. He told me the speech had been too long and he hadn't wanted to make it any longer. I reassured him and laughed it off because I didn't want it to be on his mind for the rest of his wedding day. We haven't talked about it since but I'm struggling to let it go. He talked about all the people that mean the most to him and left me off the list. I don't feel I can bring it up now that a few months have passed but it's eating away at me and making me question whether he even likes me. Am I being over sensitive? Any advice for moving on?
