What does it mean when a guy pays attention to your period?

Anonymous
My crush basically told me he's figured out when I'm on my period and when I'm not. He leaves me alone when I'm on it, and none of my other coworkers seem to know when I'm on it. They don't notice that I'm acting different, but my crush knows. Do guys do this when they like someone? It's kinda weird how he's studied it that close to where he knows whether I'm on my period or not. Like seriously, it must take a lot of studying and concentration to know when a girl is on it, especially for a guy. Anyway, is this something guys do when they like you? If it is, why do they do it? Is it like a biological thing so they can take care of you? He asks me if I need help more than usual when my cycle comes around and stays close/checks on me.
