My girlfriend lives in Vancouver.
I live a thousand miles away in San Jose, CA.
We love each other very much, and we're waiting a year to meet each other.
I sometimes feel impatient, and honestly I've broken up a couple of times, but I've always come back, and she's always wanted me back.
The truth is, space and time are only perspectives, especially in this Internet age. Eventually, we'll be able to travel between planets instantaneously, in all likelihood. But until then, I'll bide my time and stay true to her. I have stayed faithful the whole time, despite us sometimes being broken up.
I know it will end well, because both of us love each other enough to do everything we can for each other and for the relationship as a whole.
If your commitment is not only assured, but *mutual* as well, then you'll be just fine, I think.
Good luck, friend.
