I agree. Try to talk to him if you can, about your reasons for choosing a DW. We went through something similar - my dad told my FI when he called to "ask" permission to marry me that he wasn't going to Mexico if that's where we were getting married. It was a serious downer for a while, but he eventually changed his mind. My sister isn't going at all - nothing has changed her mind, and it seriously ticks me off that she won't make the effort. But whatever..it is what it is. I hope your father changes his mind too, and is there to support you on your big day. Even if he isn't, as tough as it might be, focus on your happiness and just let it go. You can't control him or make his decisions...
