I'm not going to have my father at my wedding because he never invited me to his
Is there a reason why he didn't invite you?
He said I was an accident and that he was not ready to take care of me.
If you don't like someone you don't need to go to functions with them. You are within your right to refuse to go to an event that you don't feel comfortable at.
I don't like to hurt people's feelings so I'm planning to have my father at my wedding in the end.
That's wonderful you can get past your differences and celebrate a wonderful occasion together! I'm sure your father regrets what he said, and it would be a wonderful time to make up with him.
