I think it comes with the DW territory (unfortunately). You need to say the hell with all the naysayers (hard I know). People can make a choice, dont come if you don't want to be there; besides at the end of the day you only want those that really truly want to come be there.
Are you sure about your dad not walking you down the aisle.. its not something you can ever take back so be really really sure. I would hate for you to regret it down the road.
And remember its all about you, your FI and your happiness.
