I know most people would feel this is wrong, but I don't want my parents at my wedding.
You must have a lot of resentment towards them.
I never liked my parents. I don't want them to attend the wedding
While your parents may not always be favorable to you, making them stay out of the wedding while you get married would be difficult for them to bear. Let them come and see your compassion and inclusiveness and they may just change their ways after seeing you acting in a mature and kind manner towards them.
You don't know my parents.
You are right. I don't know your parents, but I know how most parents feel about their kids. Excluding them from your wedding will leave a scar that may last for a long time. Your children will want to have grandparents and it would be helpful on your part to include your parents in now for your kids sake.
