Clue her to Free Republic and get her to read this thread. I also find it heartwarming how many people here (and I'm one!) are trying to convince you that you're better off moving on from your vegetarian-except-for-chicken, Carter-lovin' fiance. I know, 27 seems old to you now ... but believe me, you're but a pup.
Your life's ahead of you -- don't look back unless you have to. She'll get over it.
My gf or my new friend?
