My haitian girlfriend misreads the things that I say a lot. Quite often it may be a simple gesture or a sentence that gets reworded into the opposite of what it is. Does that have to do with haitan culture?

You think it's possible that a specific group of people or culture tend to misinterpret spoken words and SIMPLE gestures? That's unlikely.  It's true that some cultures understand some gestures differently, but it sounds like you and your girl  may be "out of sync" ...I may be wrong about this :-\
