Just cutting things from what you posted makes things seem almost self-evident, but people oftentimes know more than what they say.

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.

Well, I'm certainly no expert, but it seems the distance geographically isn't really the issue, inasmuch as the placement of career over the person. If career means more, to either side, than their 'love', perhaps not a good thing.

If it was me, I'd share what I could, when I could, and determine the future when circumstance or choice allows for it.
Damn, I feel like Dear Abby...
