Infatuation?

When I started my current job 5 years ago, I immediately was drawn to my supervisor. My boss was required to travel to 15 other locations, and not just mine. Anytime I knew she was coming, I'd buy a new outfit etc. Most people hate when their boss is around. Not me! She would always tell me to relax and asked why she was making me nervous. I was a hot mess around her. Long story short, I formed a great working relationship with her and I could shoot the sh*t with her. (Always going away from work issues, into other personal issues) she was my boss for 2 years, and one day she told me she was being transferred. I sobbed like a baby when she told me. I cried for a year straight on and off. It was madness. Now, 3 years later(after her departure), I still think about her. I am not irrational or crazy. I know I cannot be with her, nor would I ever try!! She's married!! I just wanna know if anyone still thinks about someone they haven't seen in years, on a daily basis.
