<human>: a little background info:
I graduated from college last year. For my first three years at college I had some self esteem issues and did not really make any connections. However, during senior year I was an RA and had a pretty good social life.
From the beginning of my senior year I had a crush on a fellow RA and did not act on it because I still had some problems with self esteem. But, the crush started to fade

. Fast forward to the end of the year, during senior week: I had some conversations with her and the crush that was fading came back. This relationship will never happen because she is out of my league and we live in different states now, but it has been a half a year and I still can't shake her out of my mind. 

I haven't been able to move on. How long will this last?

Can you condense the text into a few key points?
