My father hates my soon to be husband?

I would recommend that you have a talk with your dad. Tell him how you feel without sounding too rude and don't raise your voice too much. Also, listen to what he has to say and try to understand why he thinks what he thinks. If after that if his opinion doesn't change, just marry the guy. This may cause problems with your dad however, so you must be certain that you are prepared to sacrifice that relationship to make a decision that you won't regret. :)
