my emotional rollercoaster

I thought I had it figured out, I thought I was moving forward but everyday seeing her at work and having friendly relations with her just makes me desire her even more. It's really stupid. I wish our relationship was like this when we were back together. I wish she would smile that way towards me because she loved me romantically. 
Hope is a terrible thing when my mind and my heart doesn't go hand in hand. My mind is telling me its a lost cause to bother hoping to get back to her but my heart and it yearning is making me lose control. My dreams have also been a significant indicator of my mind.
Last night I slept fitfully but from what I remembered most in my dreams was that I was handed a video camera and in it there where contents of me being completely nude. If my interpretation is right, should I be viewing my vuneralbility in an objective manner?
I know i must fight on and continue my path to improve myself. I need to learn how to let go of this love even if she is going to be around me longer then I had anticipated.
