Why does it feel like my boss is afraid to be alone with me?

My boss and I have a weird connection. Not sure what it is. He and I communicate a lot through facial expression and eye contact on work related matters. Lately, the eye contact has been getting longer. Yesterday, I asked him for the key to lock the door to the establishment. Other workers were around. And we just stood there for a couple seconds eye gazing, with his eyes looking to and from both my eyes, as he slowly pulled the key out and hand them to me.

Then later that night, as I was the only female left working, I told him I was almost finish and was gettig off the clock, and he seemed to want to avoid me and said good night and vanished to the back where a few male coworkers where still finishing up.

He would always want me to be in charge of the workers that work in my department, even though I am not a manger, etc. And wants me to train all the new people. He gets aggravated if any of his managers don’t have me in charge of those workers.

When we are talking, our eye connection is unbelievable. And there is a mutual surge of energy that forces us to pull away. Not being dramatic, or reading too much into it. But, its so real, that he is in my dreams alot lately.

I wouln’t do anything though. I am not the type. And plus, he is married with a child.
