My fiance's family hate me?!?!?!!?

in laws are always tough, especially if they have a mind set of some sort that doesnt fit yours. Here is what you do, you need to learn to be out going and talk to them, start a conversation. If you know what the mom likes and you share a common interest or know something about it, then talk to her about that topic, same with the rest of the family. try not to show that you are nervous or whatever feelings you are feeling. Be respectful, talkative(but not to much), and just be nice, but not in a "trying to kiss your " kind of way. And make sure your fiance stands up for you because if his family loves him like they say they do, then we he stands up and says "I am 100% sure I want to marry this girl, because she is the love of my life" then they should back down, because they will understand his feelings towards you. Good Luck! and congratulations on your engagement
