Just cutting things from what you posted makes things seem almost self-evident, but people oftentimes know more than what they say.
Bottom line is that only you know the answer.
Unfortunately I am in Portland, Oregon, and she is in Boise, Idaho now, and it looks like things may stay that way for the long haul; we both have solid career paths that make us very unwieldy. That seems to be the biggest reason for the current situation.
EDIT: Ugh, it makes me feel ill to even think about it.
It sounds like you really love her, but if you did one of you would probably be willing to sacrifice and move.
So yeah, move on.
