He doesn’t follow me ; and has a girlfriend but?

he doesn’t follow me on Instagram. We work together , and I see he liked all the photos of me and my body / outfits on Christmas Day. I’m kinda sketched out. What does this mean? He’s never liked anything on my page before or followed me. We only work together. He made a point to like all photos of me and my outfit on Christmas Day.
