Why would an acquaintance match/message you on tinder?

Anonymous
Does that indicate that he is somewhat interested in you or at least finds you attractive? A guy who works at the same place I work at matched with me on tinder and messaged me first. He kept the conversation going, but yesterday he let it die out. I'm just wondering if maybe he was under the impression that I didn't like him back? I actually do find him attractive and like him--- Should I ask him out?
