OK, and you can prove you were going back for a job or similar, with a leave of absence just for a vacation? You didn't give up your home or sell your car? Just that in the current climate and administration I'd make sure you have plenty of evidence that you didn't intend to stay when you entered, particularly as you entered together. It may be seen as suspicious that your fiancée was planning on leaving you to go and live in another country.
As long as you've got evidence of your plan to return to overcome any doubts, and you're happy to not work for quite some time, then go for it. Follow the guide CrazyCat gave you above, and best of luck.
