If he is not into me then why does he check up on me?

I recently discussed with a guy friend whether or not there was more to our relationship and after denying that he liked me more than a friend and admitting he had a girlfriend despite hiding her from me for months I decided to make a clean brake and not hang out with him. However he's asked me a few times through email and text how I was, what I was up to and where I am I moving too. I feel like now that I am keeping my distance he's checking up on me and I don't really understand why.
