I think that the most you could stretch your arrangement out is five months, and that's based on the Christmas long-distance relationship breakups that were blowing up all over facebook in my freshmen year of college. Some of these high school couples were in relationships for five years. I do not doubt that these girls were cheating beforehand.
If you think she's actually wife material, wife her up and take her with.
Your kind of arrangement doesn't work unless it's sixty years ago and you were some kind of travelling military type or overseas businessman, while she was a churchgoing stay-at-home mother with five young children and a dog at home to tend to. Even then I'm sure at least one of your kids would end up looking like the mailman.
