When I was at an event I was coming from the restroom and a guy that Imwho was there at the swing dance was standing in the hallway as I walked by?

staring and smiling. Then a month later when I was at another dance I was sitting down and he came over and stood next to me, smiled and then walked away. Note: when he came over and stood next to where I was sitting and smiled my boyfriend was also there

I was wondering what it means? No rude comments please.
