Feeling really offended and not sure if i should be. Just been to a family get together with my DH's side of the family. I found out that his sister has been invited on the hen night of his brother's future wife but that i am obviously not invited. We are the same age and although i don't live locally the hen night is not local it is in London. I feel that family should be treated the same and the message is that i am not liked. I know i'll feel even worse when my husband goes on the stag night. I feel it's a chance to meet other people who will be at the wedding and i'm already an outsider for not going. Am i being unreasonable?
