My parents divorced when I was 17 when my mum left my dad for another man. Me and stepfather have never gotten along, and my relationship with my mum was incredibly strained for a long time. Only in the last year have we really started to begin to repair our relationship. I really don't want to have to invite my stepfather to my wedding, we don't get along, I really dislike him and I don't want him to ruin my day. Am I just being incredibly selfish or do I have to right to invite who I want?
