Do you got to go with her? Why doesn't she just go by herself, this will give you 6 sweet months of sweet freedom from her constant nagging, and she will get to advance her career or whatever. Granted by the time she comes back ya'll might realize that living by yourself is way better than being married and thus the whole thing will end in a divorce. Alternatively just tape her mouth shut, or start going "bla bla" anytime she starts nagging see how long it takes her to snap, make a game out of it.
