So sorry you are dealing with this. It's horrible thing that happened, however does he understand that it was anaccident? It could happen anywhere. It wasn't a bomb or an explosion done with purpose? It seems that the people that were against going to Mexico from the beginning are going to find any reason not to go. You and your fiance need to follow your hearts and have your wedding where you want, if you settle for what others want you'll regret it. I have an aunt who didn't want to go from the start and was coming up with every excuse possible not to go, one of them being " I don't like Mexican food" ahhhhhhh that one made me laugh. My cousin (her daughter) is pregnant now and is due a couple weeks after my wedding so that gave her a valid excuse not to go, but when I called to congratulate my aunt on becoming a grandma the first words out of her mouth were "Well that's it I can't go to Mexico now!" Bahhhhhhhhhhhhhhh! I was stressing about people not coming etc, but I've stopped and realized that it's about my fiance and I getting married and choosing to spend the rest of our lives together. I'm sure if this is what you truly want your dad wouldn't miss it. He's just testing you, My fiance parents didn't give us the money they promised for the wedding when we decided to have the wedding in Mexico and they thought it would stop us, but it didn't.
