Lack of interest?

So I spent about 45 minutes walking with this guy I like yesterday. I figured he’d pass me and head back, but he stopped and walked and talked with me. He told me stories and then at one point mentioned how he used to enjoy when people would pick on his ex wife (when they were married). And made the comment, “And I guess that’s why I’m single.” Anyway, later that night, I texted him to thank him for the company and say I had fun. The response back was, “well you got me out of doing work, so I guess we both win.” Obviously not quite what I was hoping for and took it to mean no romantic interest. Thoughts?
