What are some reasons guys ignore questions?

So I asked my boyfriend how is everything at work. No response. So then I followed it up with another question adding how is he and how is he doing? No response. He ignored both of my questions. Should I take it personal or is there something wrong with him or does he just want to be left alone? I want to know what the people here think before I directly ask him because he's at work rn.
