When things like this come out of the blue, I always considered it a blessing. It sucks when it's going down if you're on the wft just happened end. As for fair, as tekla pointed out, there is no fair so it's really best not to try to make it a fair/not fair thing.
If you guys only lived 2 hours away and many months would elapse without you seeing her, I'd call that a problem. You say she was your fiancee but even if you both didn't have your own car, if there were serious strong feelings there (fiancee = willing to spend the rest of your life with someone in my book) one or both of you would have gone out of your way to be by the other person's side more frequently (bus, train, bumming rides off friends, etc. etc.). 2 hours is not a hell of a long way. I think it's important that this break up came right at this time when you got a job just so that you could see her more often. She's not ready to up the ante and I think you've actually pushed her away or made her more uncomfortable by "worshiping" her and treating her "like a queen". That often backfires unless the other person is seriously shallow and vain. I think tekla also nailed it with this, "I mean you say that you didn't expect crap from her, so what was it she could give you? Many people like it when the other person needs them to do for them, help them, and all that. And you were doing everything you could to help her - yeah, everything you could do at a distance."
It's very easy to accept someone when you're not spending your day-to-day with them. It's also much easier to say things on the phone, or in texts or email than it is to say something to someone's face in-person. Serious relationships that work have a give and take. And like what other people have said, the day-to-day stuff is probably the most important.
It sounds like it was all very safe and non-committal. And I would surmise that she wasn't getting everything she needed. The fact that she told you to concentrate on your own life also points to her feeling like too much attention was put on her.
The best thing you can do now is work towards your own personal goals and as she said, work on your life for awhile. If she still wants to be friends, be there as a friend but realize that things were probably not as perfect as you thought.
