My one male supervisior had been making a lot of eye contact but since then has stopped but not long after that I caught him staring at me?

And the other day he was looking at me but I didn’t see him until I turned around and. Saw him walking away. I was wondering why he stopped making a lot of eye contact.

No rude comments please.
