I have this particularly bad habit of becoming infatuated when it's inappropriate to do so. I also find that it takes a long time for me to get over my infatuation.

I've run into this situation again, as I've fallen for someone who is entirely unobtainable. There is no way that anything good will come of it, and the longer I let myself be interested the more harm I stand to do to myself. As I've never been good at moving on I felt the need to ask for advice. Please keep in mind that I'm looking for answers that do not include anything along the lines of: with time, it just happens, or finding someone else. I've heard those suggestions before and they really don't do any good.

Well you have to move on. It's clear you can't get her. You're just stalling your own decision. You need to make up your own mind saying to yourself: "I don't want to waste any more time thinking about this person", and then move on.
