Why do you think he didn't show up?

I chatted with someone here and actually agreed to meet him because he didn't live far from me (against all my friends advice, I should add). I drove about two hours and went to the area where we were to meet and messaged him. He never showed up. He said he was working hard on a job and apparently didn't check his messages. He has apologized. I have a strong feeling there is more to the story about why he never showed up. Any ideas?
